NASA TT
I don't know the answer about the roll bars. It will probably take a little time to sort out.
There aren't a lot of MR2s out there racing. Those are wonderful cars, but the lift-throttle oversteer in them makes for some, um, exciting track time.
Not to sound too much like a shill, but look at one of the FFR spec cobras. We're finding that it is cheaper to run the Miata and only a little more expensive to purchase. The spec rules have really kept the costs down and I really can't think of anything with better performance for the money.
