Well - I have made some progress!
For anyone in the same situation, I found a Toyota OEM rebuilt AC compressor/clutch at the link below. The price is abit steep compared to other options but I figured for the hassle I would just go with this option -->

I also spoke around to some various AC shops about the price of a 134a conversion and it was quite steep ($400 range). Also, I have read that 134a does okay but generally has worse performance than r12. For the cost and performance, coupled by the fact that I just did the online test to get EPA 609 certification, I think my plan is as follows:
1) Order some r12 off
ebay - I reckon 3 lb should be more than enough...
2) Install and hookup my new AC compressor and get a new dryer unit. I will leave the belt off until all the other steps are complete to avoid burning it out running without refridgerant (if this is possible )
3) Bring the setup to a certified shop locally to make sure there are no leaks or other issues with system that need to be addressed
4) Get the r12 from step 1 shipped to my PO box on the stateside
5) Hook up belt and with truck running fill system with required amount of r12.
6) Drive home.
Anyone see any problems with this plan? I think I should be able to get the r12 for <$100 which is a significant savings over the conversion....
