My suggestion is to remove anything you want removed yourself before painting. This includes sunroof and seals, door handles and chrome, bumpers etc.

Even if you give the FSM pages to the shop, they will ignore and disassemble the way they think easiest. You can can remove and bag and tag for easy reassembly.

The other option is to find a quality shop familiar with these old cars and pay a premium if you can in fact find such a shop.

I couldn't. Lessons learned. The paint looks great but the process could be easier.
