AC Compressor Teardown/Rebuild

As part of my general overhaul, I am updating/replacing my nonworking AC system. I picked up a compressor, lines, condenser etc off of a Tn3S member that he took off of a 94 SL.

Being that he wasn't sure if the AC was working before he removed it and it has sat for a few months, I decided to open it up and check for signs of rust and what not.

Aside from what appears to be dried up freon oil, it is fairly clean in here with no obvious signs of major rust or corrosion. Aside from the clutch, which if it fails I would have to just get a remnned unit it seems, is there anything else I can or should do while it is a parts aside from clean it out?
