You already have the IMS speedway and the IMS museum on the list. Those are a must do.

You mention that you are coming out for the USAC show at Knoxville. It is a real guessing game on how many cars will be at that show. You should not set your expectations of a high car count.

The last bit of advice would be to look at your travels from night to night. It may make more sense to pick a reasonably located motel than checking into a new motel night after night.

Midget week is a great show because at most tracks 410 Sprints are the support class.
