The distance will require upsizing the wire to compensate for voltage drop. I'd probably target 60A -- you can still use a 100A panel in the barn, but feed from a 60A breaker in the main. At that...

Unfortunately no. There is a massive price jump between 60A air conditioner disconnects ($10) and 100A disconnects that will probably be over $100. The search terms you'll want to use are 100A,...

The existing installation is over-fused; #8 copper should not exceed 50A. With kitchen facilities in the outbuilding, I think this feeder is too small.
