Tips/advice? OK...
1) Have fun.
2)Don't expect your flight sim skills to transfer directly to the real thing, and be patient with yourself if the reality of this frustrates you (as it most certainly will).
3) Remember always that your instructor and flight school are working for YOU. Make sure you're getting what you're paying for; know what the minimum requirements are for the PPASEL check ride; question (respectfully) any "extra" dual or review work, etc. And if for some reason the school or CFI "disses" you, don't be afraid to change schools mid-stream. DO NOT PAY FOR LARGE CHUNKS OF INSTRUCTION AHEAD OF TIME, FOR THIS VERY REASON. Screw the discount...more than one young student has shown up for a lesson after plunking down thousands of $$, only to find that the school has closed down. And good luck getting your money back. In general, these deposits are not refundable, even if you decide to leave the school for some other reason. Pay as you go, and make good use of the time you're paying for... it's a better way to go.
4) As a personal favor to this old pre-GPS pilot, make sure your instructor teaches you how to navigate primarily with compass, clock and chart, and make sure he or she knows the difference between ground speed and airspeed (many do not).
5) you may, in ground school, hear some stuff about Bernoulli, Coanda, or Newton. The FAA likes to have you memorize this nonsense, but rest assured, it's all lies. the thing that keeps a wing in the air is
money! 
6) HAVE FUN!!!
