New to the game. Need some beginners advice.

I have always been in to audio. I asked for a receiver and a pair of 10's for my 12th birthday. I have always been a receiver kind of guy. Now, I want to do it right.

Can someone point me to a resource that can list the different components of a typical audiophile's system and their functions? I am trying to get away from just a simple home theater receiver and get more out of the speakers I own (I have the full Jamo D8 line). I have the ability to purchase some used Adcom and NAD amps from a friend at a great price according to the bluebook, but I need some advice on starting out. Any help is appreciated.
