To add to this:
1) don't buy one yet unless you plan on doing this alot. No point in spending 100+ on a helmet and only using it once.
2) Most beginners won't know what to do with tire pressures, but it is good to fill your tires up before and event. Have a pressure gauge, either digital, or the dial type. None of those cheapy 99 cent stick type ones from Autozone.
3) Numbers are always good. I think SCCA states they must be a minimum of 8" tall and class should be minimum of 6" tall. If not there is always painters tape on the window.
But the most important thing is SEAT TIME. Seat time, seat time, seat time, and when you think you've had enough seat time, go to another event and get more seat time. Also, talk to and get to know the seasoned vets, most people are more then willing to help out the new guy.
As far as mods I wouldn't worry about anything to start. Just go out there and run what you have and get experience in it. Because certain mods will throw you into some pretty high classes. Just get out there and have fun, get better, learn your car, then start applying modifications to help you get around the courses faster. But without a baseline to go off of, you'll have nothing to compare it to.
Oh, and one more thing, GO SLOW TO GO FAST. I can't stress that enough. More power and more speed then the other guy does not always equate to a win. Autocross is a technical timed event, which means the better you take a line, sometimes taking it slower then you think, the better you will do. I've seen people go out there and blow through turns because they though faster is better.
It's better to get the car balanced going into the turn slower, rather then understeer right through the other side of the turn. Slow in, power out. Brake in the straights. If your not on the brakes, you should be on the gas.
But most important, SEAT TIME.
