I would most certainly hook it up if it had it OEM. I will let one of the more experienced guys on here help you with the set up but they will need to know if it is electric or pressure. If it is electric I would not trust that is is already set up right either.
Did you check the oil level again. If you had oil stuck in the evap cause of the failed compressor you will be over charge once it comes back. I would check for acid also due to they way you described the oil color. A high acid drier might of helped you out here also.
