Sears put out a book titled Power Router and Hand Tool Know How (#9-29116) that has a lot of good info in it. My copy was published in 1993 so it may be a lot out of date. There are many really great books on the subject that you can get from the major booksellers like Barnes & Noble. Perhaps someone may also be kind enough to post the link to the page on the Sears site for the exploded part drawings and other info that is probably there.
I would sure agree with Steve that the bits are a major part of using a router. Don't even think of using tool steel bits. I buy many of mine from MLCS at www.mlcswoodworking.com and find that the quality is great and the prices much lower than many other sources. It really gets to be funny when you hear from the pros that these aren't any good but the magazines show that they do the job in side-by-side tests. But tool steel and worn out carbide bits will turn you off trying to learn to use your router quickly so, if you do need bits, buy good ones to start.
