what all is required for an R134 conversion (parts numbers, prices, etc.)?

I don't know what the situation is in the states, but over here we can get "Drop In" R12 replacements. These are gases which you can use instead of R12 without needed to modify your A/C system.

I had mine filled with RS24.

I'm told that the best stuff to put in is ordinary butane, but I think this is illegal in the US because it's flammable. (Unlike all the other fluids in the engine bay?

I had my system recharged with 134 when a failing AC hose was replaced. The only hardware required was a new filter/dryer (which should be changed whenever the system is opened), and the aftermarket part (NAPA) cost around fifteen bucks.

BTW, my AC is COLD.

I know autozone sells a complete retrofit kit for $30 (I bought it for the rx-7). You need to have the system vacuumed out first to remove the remaining r12. You can then swap out the dryer filter. Then you put a r134 adaptor on your low side valve (comes in kit). After that start the car and ensure the ac compressor is engaged, connect the can of regridgerant/oil to the low side port, then let the system suck the stuff from the can. I'm pretty sure you want to reach about 50 psi. The instructions that come with the kit are a lot better than me decribing it, but this is the basics.
