This Page is probably the most inclusive source on the net. But it's 2 years old, so some rules have been added, removed, or changed...and it doesn't include Prepared and Modified class rules (which likely won't matter to you anyway).
You have to purchase a rulebook if you need more than that page can give you.
BTW, anybody with a '04 rulebook want to see if I need to add/remove/change anything in this guide? It's based off the '03 book.
