Welcome Noobie, Just start hanging out and read all the threads. You have a lot of questions and if you read the all threads, you will have only a couple of questions that will need to be addressed.

I recommend checking out Ar15.com if you haven't already, lots of black rifle info there.

[MrMurphy]

Yes, but we won't rip his head off for asking "noob" questions, like they will.

My favorite source for vanilla consumer type builds is JSE Surplus out of MO. They have even better prices at the gunshows they attend and will bring you stuff if you email them preshow.
Other than that, I'll echo the other posters' questions.
