The following items are listed in groups because the are only used together. Chances are that if you aren't using one, you aren't using any, so you can disable them all. (I have tried to note whether each item is an extension, control panel, shared library, etc. by noting the type after the item's name.)
APPLE GUIDE:
Actually, only the Apple Guide extension takes up system RAM; the individual modules, called "mixins," are documents. But for those of us who just want to keep things neat, you can remove all of them: NOTE: There is a known bug in Apple Guide. If you are having trouble with Apple Guide functioning properly, make sure you don't have mixins installed for items that are not on your computer. Some examples of this: having the "PowerBook Guide Additions" on a desktop Mac; "Speech Guide Additions" on a Mac not running PlainTalk; AV-related mixins on a non-AV Mac. To solve the problem, just remove the offending mixins. (Thanks to Bob LeVitus and Chris Breen for this tip.)

窶｢ anything with "guide" in the name is probably an Apple Guide module
You may see Apple Guide modules that come with other applications; unless they are installed in the extensions folder, or you are specifically told to move them to the extensions folder, leave them where they are. Some modules belong in particular places, in which case the application tells Apple Guide where to look.
APPLE REMOTE ACCESS:
窶｢ Apple Remote Access Client (Ext) (v2.1) [NA]
窶｢ Dial Assist (application posing as a CP) (v2.1) [NA]
窶｢ Link Tool Manager (Ext) (v2.1) [NA]: supposedly improves the error correction handled by ARA.
窶｢ Modem Link Tool Personal (Ext) (v2.1) [NA]: uses the "Modem LinkTool Personal" documents to allow ARA to work with various modems.
窶｢ Serial Port Arbitrator (Ext) (v2.1) [NA]: Provides ARA with the ability to prevent other applications from using the serial port while ARA is active. Allows more than one application to use the serial port if ARA is configured to answer the phone. Incompatible with Serial DMA before System 7.5.3. Newer version of Serial DMA, which is built into 7.5.3, is compatible.
AT EASE:
At Ease allows you to set up your computer so that users can only use certain applications/ folders/ documents. It also prevents them from accessing and reconfiguring the system.
窶｢ At Ease 7.5 Layer Patch (Ext): When "Show Desktop when in background" is not checked in the General Controls control panel, the System software "hides" the Finder when another application is in the foreground. At Ease, on the other hand, tries to stay visible in the background when an application is launched. When both of these circumstances occur at the same time (using At Ease with the "Show Desktop" box unchecked), the Process Manager in the System software can't decide whether to "hide" At Ease or not and crashes. This patch fixes this problem.
窶｢ At Ease Items: this folder, stored in the System Folder, contains all the user info and preference files for At Ease.
窶｢ At Ease Startup: extension which causes the computer to startup in At Ease instead of the Finder.
GEOPORT/EXRESS MODEM & APPLE TELECOM APPLICATIONS:
The Geoport adapter/modem and the Geoport software apparently only work on PowerMacs, PowerPC Performas, and the Centris/Quadra AV models, which all have the enhanced Geoport serial ports. Note: For Power Macintosh 7200, 7500, 7600, 8500, and 9500 series, version 2.1 or higher of Apple Telecom Software is required. If you are using a GeoPort Telecom Adapter on these Power Macintosh models, Apple's Telecom software will not work if you have any LocalTalk devices connected to your Mac. Simply turning off AppleTalk will not solve the problem; you must physically disconnect any LocalTalk devices. Serial printers can remain attached.
There are actually two "sets" of extensions installed by Apple Telecom 3: the GeoPort/ Express Modem software and the Apple Telecom software. They are listed below. If an item is followed by a configuration, it means that the item is only installed on systems with that configuration.
GEOPORT/EXPRESS MODEM:
窶｢ AudioTuneUp (Ext): GeoPort/Power Macintosh 9500 series with System 7.5.2 only.
窶｢ Apple Telecom Modem (Ext) (v3.x) [NA]: enables the Geoport pod and serial port.

窶｢ Express Modem Tool (comm tool) (v3.x) [NA]
窶｢ GeoPort for Power Macintosh (shared library) (v3.x) [NA]: GeoPort/Power Macintosh configurations only. Installed by both the Geoport modem and the QuickTake camera. Needed on all PowerMacs, including the newer PowerBooks, for the Geoport modem and/or QuickTake camera to work.
窶｢ GeoPort Serial Driver (shared library) (v2.0) [NA]: GeoPort configurations only. Installed by both the modem and the QuickTake camera. Supports the use of the serial port by the Geoport modem.
窶｢ GeoPort/Express Modem: Apple Remote Access CCL/modem script
窶｢ GeoPort/Express Modem CNG: Apple Remote Access CCL/modem script which adds calling tones to the modem signal. If you dial into a system that handles data, voice, and fax calls, these tones allow the machine you are calling to detect if the call contains data.
窶｢ Serial Extension (shared library) (v2.2) [NA]: GeoPort/660AV/840AV and 6100/7100/8100 series only
窶｢ Serial (Built-in) version 1.2.1 (Ext) (GeoPort/5400/6400 series and 6360 only)
窶｢ Shared Library Manager: GeoPort configurations only. See entry in the "Extensions" chapter. Note that this extension is also installed by other software, including Open Transport, so don't remove it unless you're sure you don't need it.
窶｢ Shared Library Manager PPC: GeoPort/Power Macintosh configurations only. See entry in the "Extensions" chapter. Note that this extension is also installed by other software, including Open Transport, so don't remove it unless you're sure you don't need it.
窶｢ AppleScriptLib (v1.2.2): See entry in the "Non-RAM" chapter. Note that this shared library is also installed by other software, so don't remove it unless you're sure you don't need it.
窶｢ CFM-68K Runtime Enabler: 68K computers only. Allows 680x0 Macs to use the Code Fragment Manager. Note that this extension is also installed by other software, including LaserWriter 8.4, so don't remove it unless you are sure you don't need it.

窶｢ Log Extension (shared library) (v3.x) [NA]
窶｢ ObjectSupportLib (shared library) (v1.1): see "shared libraries" in the "Non-RAM" chapter. Note that this library is also installed by other software, including AppleScript, so don't remove it unless you are sure you don't need it.
POWERTALK:
窶｢ Apple Fax Gateway (Ext) (v3.x) [NA]: not installed by PowerTalk, but by the Apple Telecom Software. Allows you to send faxes over PowerTalk

窶｢ QuickDraw 3D (Ext): basic QuickDraw 3D extension, contains both PPC and 680x0 code.
窶｢ QuickDraw 3D Accelerator (document): contains PowerPC-native patches to the basic extension. NOTE: this file is supposedly only installed on systems where the installer detects a hardware accelerator card.
窶｢ QuickDraw 3D RAVE (Ext): stands for "Rendering Acceleration Virtual Engine." Allows applications to use QD3D hardware accelerators (PCI/Nubus cards) with their existing 3D rendering engines.
窶｢ QuickDraw 3D Viewer (document): provides the viewing system for QD3D applications. This includes the standard icons for switching between rotation, translation, etc. Also contains the code for the graphics interface which permits viewing 3DMF objects. For example, SimpleText uses this interface when loading a 3DMF object.
QUICKDRAW GX:
窶｢ EPSExtension (Ext): Encapsulated Post-Script printing extension. Allows you to save a file printed using the LaserWriter GX driver as an Encapsulated PostScript file for importing into applications that do not support QuickDraw GX, such as Aldus PageMaker and QuarkXPress.
SPEECH/PLAINTALK:
NOTE: The Speech software can cause a Mac Plus (which does not support speech) to hang during startup. To avoid this problem, restart with extensions off, remove the Speech software, and restart.
窶｢ Macintalk 2/3/Pro (v1.4): a "document" which allows the computer to read text in human voices (2 and 3 require Speech Manager and the "Macintalk 2/3 Voices" files; Pro requires Speech Manager and the "Voices" folder in the System Folder with voice files installed); . Pro is for 68040 and PowerPC Macs; 3 is for 68030, 68040, and PowerPC Macs; 2 is for 68020 Macs and Macs running pre-System 7 system software.
窶｢ My Speech Macros: supports the Speech Macro Editor to allow you to create your own speech items

窶｢ Speech (CP) (v1.4.1) [0/0]: allows you to change between installed voices in applications which allow "speaking" (i.e. the "speak selection" option in SimpleText); also used to set options for giving your computer spoken commands
窶｢ Speech Manager (Ext) (v1.4) [7/320]: when used along with the other software here, allows your Mac to speak written text
窶｢ Speech Recognition (Ext) (v1.5) [45/52]: enables speech recognition. Version 1.4.1 is installed with the latest PlainTalk installer. Version 1.5 fixes bugs with PowerPC PowerBooks using the built-in microphone, fixes a bug with PowerPC Performa models where sound output would be muted, and includes other minor fixes. It is available from the following URL as part of a special "full" install, or by itself:
ﾂ <http://speech.apple.com/speech/ptk/ptk.html>
窶｢ SR Monitor (Ext): used to monitor and interpret speech
窶｢ System Speech Rules (Ext): supports voices and speech dialects

窶｢ Voices folder (found in the "Extensions" folder): contains voices for use by Speech/ PlainTalk/ Text-to-Speech
WORLDSCRIPT:
InputBackSupport, World Script II, & PowerAdapter, and the Japanese Language Kit extension are all a part of the Japanese Language Kit, and (except for the JLK extension) presumably other language kits as well. If you are using the standard English system, and not using anything like one of the language kits, you can trash these.
窶｢ InLine Filter (Ext): allows inline input of characters, as opposed to manual entry into the input bar.
窶｢ InputBackSupport (Ext) (v7.5.2): provides support for two-byte fonts. Allows complex character entry, including text pre-processing to allow multiple keystrokes to be used to generate a single character. Also supports Japanese fonts already in use that aren't TrueType fonts. Provides backwards compatibility with Japanese 6.x input methods.
