Best bit of advice I can give, aside from all the other comments, is to make your first time racing at the track on a test and tune night. Usually the atmosphere is a little slower, no great rush to get everyone's time trial in before eliminations, not as many cars typically, and you can embarass yourself in front of fewer people in the stands. Get the bugs out of your car, and you, on test and tune nites. When you are ready and know the drill, try elimination day.
