Track work is fun nomatter how fast the car, mine has 63rwkw and I had an absolute ball. There isnt really much that can go wrong if you know the limitations of your engine and keep the car cool and dont over rev it etc.
Yea you do, for track days you only need level 2 non speed which is approx $60 a year, same license for motorkhana, khanacross and drifting, not that ive ever done drifting. To get the cams licence all you need to do is be a member of a car club and fill out a form for it.
