A/C compressor/drier swap out

My A/C hasn't worked well since the day I purchased my '01 v6 rodeo. Now the comrpessor clutch is now grinding and the ac blows warm when you come to a stop. It does get progressively cooler the faster you drive. It does maintain great pressure though. A friend has suggested I replace the compressor and the drier. Would I need to replace anything else since I'm going through all this trouble? Also, where is the drier located? Thanks

You could probably get away with replacing just the clutch and then have the system recharged and leak sealed.

Drier is behind the grill, near the radiator.
