For the manufacture date, I think you may be able to get this either from the door panel serial number, or VIN Number - Can't remember the particularities from the top of my head, but you should be able to decypher the door sticker; VIN Info can be found on the internet.
As for the compressor, Did they attempt / complete a regas? If so, And it is retaining pressure, You could be worth shimming the compressor clutch - Might save you buying a new compressor.
