I believe the test and tune is just that... folks with new tires, springs, suspension, whatever test and tune on the track to see how the changes impact lap times.
As for just driving the auto-x, you just need a SNELL certified helmet. And take out all the crap from your car if you're coming, since nothing can be inside the vehicle when you drive.
Other items -- bring a chair, sunscreen, drinks, camera, etc. There is some waiting around from time to time, and there isn't much shade in a parking lot
