Is there any air conditioned seating?

Yes in the suites.

Yes, there is seating in the luxury suites. If you are familiar with the park, these are the buildings that are at the very back of the normal stadium seating. Concessions and stores are on the first level, and the luxury seating and boxes are above.

In the suites, the JCPenney club, and at least some restrooms.

Yep
