need a lesson in A/C

Ok...somewhat back on track. So I was able to hotwire the compressor, and it kicks on, but its not blowing what I would consider cold air. So that being said, the compressor is "good"? Probably just a leaky o ring?

So...guess I will keep it. Replace all the o-rings as you suggest. Flush the system. Replace the drier, and then find someone to fill it?as I imagine thats a one and done, and requires special tools?

If you are talking about filling it with R12, yes. That would work. That's what it sounds like has happened. The refrigerant has leaked out. You will need to find the leaks and repair them before you recharge it, though.
