Welcome bro.
Be cool, relax, don't get too anxious for all the answers too fast. Take a moment to look around and read a lot. If there's a topic you want info on, do a search first. Redundency tend to piss people off a bit.
Definitley check out StewMeat's post at the top of the board about how this runs. There are some really knowledgable people here (Like Stew) who you'll be very thankfull you'll get the chance to share their knowledge with them.
And, don't be afraid to ask a Moderator if you've got questions about stuff before you post anything that may get people on your back.
Everyone's here to help eachother, so take your time to ask and do research.
