Welcome. I'm in about the same boat, I'm learning more and more every day. This place is great for it, most people on here are eager to help.
Lots of good stuff going around here too, so keep your eyes peeled.
As a tip, think about what you really want from your system. [IE loud obnoxious, beautiful and clean, ect.] A lot of people on here have a lot of experience and won't steer you wrong, you just gotta know what you want.
