Get your breaker to match the rating for the compressor. Add up the amperage for all circuits to see if you're still under the max rating for the main. Elsewise you'll need a second box. Other than that its pretty straight forward. Even with my air compressor (80 gallon Campbell Hausfeld 30 amp breaker), and the oven (9900 watts 30 amp) running at the same time I've not had any problems with breakers popping in the house.
