dood, I can see that you're just too exited and just want to get right to the good stuff... im sorry but it's just not like that.
if you want to learn, start by building a simple, cheap, reliable project. a cmoy is just perfect.
there are many many many things that you need to learn in order to get to the point that you want to get to, and first on that list is learning how to read a schematic, thats like the most basic knowledge you'll need. if you dont know how to read and UNDERSTAND a schematic you wont be able to build anything, mostly because as a noob you WILL run into problems, and you need to know what you did wrong and where.
Do it the fun way, go step by step, don't rush it, just build a simple and cheap Cmoy, when you finally get it to work you'll have learnt a great deal of really valuable stuff, like how to read and understand a schematic, how op-amps works, what is ground, what is a negative and positive voltage, whats a bias voltage, whats oscilation, how to solve it, whats dc offset and why you dont want it in your phones (by the way, never test your builds on your expensive phones, use crappy earbuds or something like that for testing) how gain works, how to wire pots, how to solder caps, resistors, diodes, ICs and possibly your fingers....
Then you can go onto things like a ppa or a mini3, or a crossfeed or many other things.
Cheers!
