Are you going for commercial eventually? If so you're going to want to get a class 1 medical certificate and its best to get this ASAP. All in all in took me about 6 months to get mine - 2 weeks for initial examination then all the rest waiting for follow ups (which proved to be nothing as they expected (best to be sure obviously)). This obviously set my solo flight back quite a bit.
Other than that get studying (Air Law first) and have fun!
One other thing I'd advise getting you're own headset quite soon; I always find that most borrowed ones from the club pinch the top of my head. My reconmendation would be the David Clark 13.4 - simply love it. On top of the comfort is the deseases that can spread in borrowed sets. However having said all that make sure you have a couplel of lessons first to make sure flying is for you.
