There is one more race weekend left on Oct 4/5. The best way to answer a lot of your questions is to come on out to the track and hang out in the pits. Everyone is very friendly and willing to tell you everything they can. Better yet, get your feet wet at the track by marshalling a corner. Watch the action real close. Free camping too. (Although Oct may be a bit chilly...but we have accomodations for trailers as well) I didn't know a single person at the track when I started going , now I'm racing and made a lot of solid friends.
