I suggest anyone interested in using this system begin with Leslie Lamport's LATEX system and the accompanying manual LATEX User's Guide and Reference Manual, published by Addison-Wesley. After using it for a while, you will doubtless eventually want to do more sophisticated work with it, at which time you should get a copy of Knuth's The TEXbook, also published by Addison-Wesley. If you use extensive mathematics, you may also be interested in Michael Spivak's The Joy of TEX, which documents the AMS-TEX macro package. As TEX's popularity grows, there have been an increasing number of other getting-started books, which are available at many bookstores.
