Putting the compressor in the shop is a very good idea. I always encourage operating the compressor in some sort of building for several reasons. 1. pump runs cooler, 2. you can better check and monitor the daily operation of the pump system, 3. pump will be easier to change filters and/or take out of service for periodic vane rebuilds. 4. Pump will receive less influence and stress due to weather.
The 3/4 hp rotary is a very good choice for larger ponds. It produces close to twice the amount or volume of air as a 1/3 hp rocking piston.
