Look for used 2x4's and some white or bright yellow paint. It's a start. You can find used crap laying all over the place that people will be happy to have hauled off. A leaf blower would definitely be good. Post an add for the generic items you need on craigslist or Houston area freecycle. The starting grid has a forum just for track issues.
I'm probably going to run at Mike's. It's clean and you can run 1/8. A lola body seems to suck the goo right off of the parking lot and deposit it on your chassis. Regardless, I may be able to lend a hand or throw out some ideas. I have a touring car I wouldn't mind running there.
