You will be cutting it close, but should be ok. I'd recommend sitting closer to the top at F! to get out as quickly as possible. It's definitely worth getting to CV early to settle in with a drink and check out all the props before the show starts. Tables are pre-assigned, so no need to worry about getting a "good" seat (and the crowd is so small, they're all good seats). CV was exactly 2 hours when we went in February, and yes, they'll have busses running to get you back to BLT when you leave, though you'll probably be sharing with other guests going to MK resorts.
