Lug-nut. Welcome to RCU and flying. This a great source of information for beginners and others. Take some time to look around the different forums that are available, lots of good stuff...
In addition to RCU and your local hobby shop (LHS), another important source of information is local fliers. The best way to hook up with them is either through your LHS, or the Academy of Model Aeronautics (AMA). The AMA web site has a club locator that might help you find a local club:
http://www.modelaircraft.org/clubsearch.aspx . Don't be shy about contacting a local club and going out for a visit. Modelers in general are very friendly and most of us seem to have an ingrained desire to help people learn.
