I got my o rings from the Audi dealer.

The file posted above answers most of your questions. I would add that you can use PAG or POE oil. Some say POE oil is the better one to use in R12 to R134 conversions.

There's no need to change the fittings on the back of the compressor, just fit R12 to R134 adapters to your high and low side ports.

The oil in your R12 system is a mineral oil and it's important to drain it out as part of the conversion. Fit a new receiver/drier when you do the change.
