Ed,
I'm glad to see you are going cone chasing this weekend. I think you will love it. On tire pressures, if you talk to 10 different drivers you will probably get 10 different ideas. Here's mine:

For the first few days run an extra 5psi over factory settings in each to prevent sidewall rollover (tire damage) as you learn the sport. You are already there. Don't worry too much about lap times at this point. As you get better and smoother you can run less and less pressure and get even better grip without rollover. Ask your instructor to show you how to chalk your tires and check for rollover after each run. Have fun!
