Air pressure depends on track conditions. If its tacky go with about 10-12 up front and 8-10 in the rear. If it's loose start with 6-8 up front and around 6 in the rear.
for gearing if it's a smaller track go with 14/39.
drop the rear as much as you can. your ride height should 1/4-1/2" lower in the rear than the front when you'r sitting on the quad in a normal riding position.
if the track is big and your running wide open all the time it will get a little hot. most flattrack races aren't that long though. if you run good race gas and have good coolant and a working fan you should be alright.
