Am starting this project, the bike has been unused for 10 years. I've pulled the tank valve out for cleaning, it wouldn't open/close. The primary/reserve tubes appear to have had some clear membrane that is disintegrated. Do I need to replace the whole thing?

If you have to replace the petcock/tank valve spend the extra $ and go with a Pingle. Well worh it. Good luck and let the fun begin.
