What is a good resource for a beginning digital producer/DJ?

Background: I'm 15, played the piano since age 7, and just started with Cockos Reaper and Virtual DJ. I have perfect pitch and a sense of rhythm so what I learned so far DJing wise is how to beatmatch and sync keys. I can also set up drum patterns and chord progressions, but synthesis is all new to me. So, I have a lot to learn about DAW's and all of the techniques used by electronic musicians in the studio and in their performances. What's a good place to learn how to work Traktor or Serato in order to play house and dubstep music?
