If it's just the clutch bearing, I know that can usually be replaced separately from the compressor, so you don't have to open the system. It's usually not much more money to get a whole new compressor (with clutch) however. For what it is worth, yours will take the R134a refrigerant which is readily available. (although still illegal to discharge to atmosphere, if I recall) Even if a Shop does this whole job for you, I don't think it should be all too expensive.
Although it's possible that both the compressor /and/ the clutch are noisy, it will usually be one or the other. (is it quiet when the AC is running? then it's just the clutch bearing!)
If you don't already own one, a cheap automotive stethoscope is great for tracking stuff like this down. (

Bill is right in that the idler/tensioner pullies are a common failure point, but they're also dirt cheap, and easy to replace. So it's really the failure you'd prefer to have..
Alternatively, if A/C is not a priority for you, there's a few ways you can simply bypass it by getting a shorter belt, and routing things a bit differently.
