The amount of oil and refrigerant should be on the info card on the core support.

Scott if you plan on doing this on your own you will need gauges and a vacuum pump. Do you have a good air compressor?
When are you planning to do this?

No, that's not a banana in my pants.
The info card on my core support cover has peeled off. 
I am lucky the belt diagram is still there. I have to look at it each time I put the belt on. 
And no I do not have an air compressor, but my Father in law has one I can use if I have to. Its a small one though like 8 gallons or less. And not sure exactly on the timeframe. Depends on when I can get all the parts I guess. It will.be at least a week or two before I even can get them.

Well I have gauges and a vacuum pump you can borrow, plus freon if you need that too. I don't think I have any oil though. My vacuum pump runs off of air that's why I asked about a compressor. If you can wait until the end of the month when I get back home I'll ship the gauges and stuff to you. I won't be home until the 28th or 29th though. The offer is there.

If I can manage to get a shop to suck out all the refrigerant, where do I go.from there? Can I just replace the compressor, drier, and orifice tube and recharge it, or should I let the shop recharge it?
And what do you need a vacuum pump for?
Forgive me but I am COMPLETELY clueless when it comes to AC systems. If this were a remote start with automatic window roll up and all, it would be a cakewalk for me.

If that will save me a few hundred bucks, I will probably take you up on that offer Jarrod.
AS I understand it if you put the system (once completed) under a vacuum it removes all moisture trapped anywere in the system. 
Yes you can just replace the components, but with a suspected burn out compressor I would also buy a gallon of denatured alcohol and blow it through the lines to clean things out, before you install the new drier and orifice tube though.
Install all the new items and use the vacuum pump on the system to draw a vacuum on it. The vacuum will help to remove any moisture trapped in the system from the lines being open to the atmosphere. Leave the vacuum pump on it for a few hours, then close the system up and see if it stays in a vacuum. You are checking for leaks, if the system holds vacuum for an hour you are good to add oil and refrigerant.
There are bound to be some how to's on youtube on charging a system. I'll have to look.

See I am not even sure WTF is up with my compressor. With a belt on it, as long as the engine is at 1500 rpm or lower it works fine and blows ice cold. 
Once engine rpms get to 3k or more, the belt and tensioner shakes so violently that it breaks the tensioner. I believe the term the TSB used was "slugging" .

See if you can rent an electric powered vacuum pump. I've seen them at rent-alls for about $8 bucks a day. Unless you've got a air compressor that supplies plenty of air continuously, you generally have trouble boiling off all the moisture in the system with the air operated ones
