Kathy gave you some good advice already. The only thing I could add is perhaps it would be wise to get a personal training for a few sessions. Tell he or she upfront that you are very new to strength training and that you are looking to learn about proper form. Ask if they can set up a program for you to follow and after a given amount of time, you could hire them again to check on your progress, double check your form and set up a new program for you...then continue on from there.
If you go the book route, a good book is "The New Rules of Lifteing for Men" by Lou Schuler and Alwyn Cosgrove. It's a solid book!
