Autocross instructors are usually the fast guys in the club. You ask around for somebody who might be willing to give you a bit of instruction and go ask them very nicely if they could help you out. Usually they'll say yes, sometimes they'll ask you to put it off for a run or two if they're really gunning for their fast time of the day.
Worry about your car at autocross? Not really, unless things go very badly wrong- usually when you're pushing way too hard and are half out-of-control in the first place. Road course stuff is much higher speed, much lower margin of error, long run sessions and much more wear and tear on the car. Anybody can autocross any car; road courses require a higher level of driver skill (from a safety perspective) and car preparation. You have to make the choice, whether it's worth it to you to run your daily driver on a road course.

If you plan on doing many autocrosses in that SRT4, you might want to consider reverting it back to a stock tune for the runs, 300+fwhp turns into major understeer on a tight course.
A friend of mine does the same for his stg 2 GTI, and he usually can pick up about a second per run with stock mode running. I've seen stg 2 SRTs run and they really have to be light on the gas and tiptoe through the corners or they go straight off the course.
