First, welcome to Flyertalk. Second, I'm sorry to burst your bubble, but please don't get yourself excited about AA domestic first class. It's roughly equivalent to intra-European business class (better seats, worse/no food), i.e. better than coach but nothing really special, far inferior to international business class where you'll be spending the bulk of your time. Have a look at the myriad complaints over in the AA forum and you'll see what I mean.
That said, it will earn you SCs as A class and is a good deal better than coach.
Enjoy your trip.
Michael
