You don't have the remove the belt from the compressor to turn it. Just grab the front of the clutch and give it a turn, this turns the inside of the compressor. This probably wont tell you anything unless it is a bearing then it might feel kind of rough. I have found that making a diagnosis from the way the compressor turns is a bad idea.
You could carefully put a long screwdriver (2' or3') on it while it is running to verify where the noise is coming from, or buy a stethescope at the local parts store to help locate the noise. But definitly check the tensioner.

I removed the belt to get better access. The tensioner and clutch pulleys turned smoothly without any play, however when I tried grabbing the front of the clutch to turn the shaft, I was just barely able to rotate it. It feels like something is seriously binding up inside the compressor. I think I'm lucky it didn't freeze-up on me.
It looks like ACKITS or ACSOURCE are good sources for rebuilt units.
Also, after I've removed the compressor, what should I look for to determine if I need to flush or not?
