Welcome on board mate! Its the best thing that you will ever do!
Apart from the advice given above, all i would add is make sure that you take a camera with you on every flight. Even if you only think that you are doing circuits. I didnt on my last flight, and i ended up going to the south lakes and it was lovley! and i had no camera because i though i would only do circuits for a bit, DOH! You never know when you will need one.
Keep at it mate and good luck!
