I originally found this on the WotC forums, but the guy who created it stopped updating it after KOTOR came out. I've since took all of the information and updated it to include all of the source books through Clone Wars Campaign Guide. The PDF is pretty straight forward - all of the classes, pristege classes and Force talents are listed along with an explaination of what they do. It is a great tool for both players and GMs!
The Maker willing, I will continue to update it as the new books come out.
