There is a good chance that the compressor isn't damaged at all. All modern automotice A/C systems have a low pressure cut-off switch to prevent the compressor from running in the event that the refrigerant runs low, or completely out. Grab a can of R-134a refrigerant (they sell them with the gauge built on to the can these days) and hook it up. Turn the A/C on in the car and begin filling the system, once the pressure reaches a high enough level in the refrigerant system, the compressor should kick on (you'll hear it click and start to run). That should answer both questions. :)
You will have to replace the refrigerant, but not the engine coolant.
Nothing will happen if you drain the cooling system and replace the coolant.

Just had to fix mine so I know. It uses R12. I had to replace my compressor so I had it modified to134a.
Open the drain out valve at the bottom of the radiator to allow the coolant to run out. Replace the valve and add the fresh coolant.
