Archetypes and Prestige Classes

I purchased the core rules, ultimate magic, and advanced player and race guides... Where are the archetypes and prestige classes at? Is there another module I have to buy for that? Or do I have what I need and just need to learn where to find them?

Either way, I need help finding the information I need to make characters that players will want to play.

Thanks.

Archetypes should be in the special abilities section. You will have to manually change the powers out however. The prestige classes should be in the class section. Both of these require you to actually have the books open in the library.
