Interesting,
Never heard of a shop adding teflon tape to fittings. I think the fittings are flared in addition to the O-rings. As an aside, a plumber once asked me why I was adding teflon to a flared fitting. If you need teflon, the connection is no good to begin with according to him. Don't know if that helps.
Schraeder valves? Why not change them since the system is open anyway? I'm not sure why you wouldn't.
How come you are converting? The AC guy I used recommended against it. He said the R12 did a better job cooling in a system designed for R12 than using R134A in a system designed for R12.
I haven't had any bad issues with my R12. I know it costs more, something like $60 a pound rings a bell, but it does cool well.
Just my 2 cents.
