Well, 6 events under my belt in my 96 SE and the biggest difference still between me and the SVT that always shows up is the driver. (He is much, much, better than me.) We both run on stock suspension and street tires.
First event? Squeal away and try to learn at least one thing. Save the tire hunt for next year. I put 2 events on all-season radials, and then spent the winter looking for a new wheel-tire package.
Dynamically, you have less power and a little more understeer than the SVT, but of course for the 99 year SE you are supposedly sprung more softly than I am. Bummer.
As for shifting, depends on the course. I've only hit 3rd on a couple of courses with longer straights or long runouts at the end. Otherwise there just isn't the opportunity.
If you find yourself pushing way off your line in a tight corner, brake earlier on the next run. This will get the car slowed down with enough time to settle in before the turn, making the most of all four of your tires.
Don't be afraid to downshift. Very useful for making the most of your power coming out of those little hairpin turns. Can't heel-toe? Don't worry. That will come later.
Otherwise, just go and have fun.
