Question I have is with a rubber roof that is basically glued down, is their any issues with gluing these mounts to the rubber roof?

I wouldn't consider that. You're gluing these mounts to a membrane that's just glued to wood, and sometimes not all that well.

Don't be fearful of drilling your roof. There are a lot of holes there already, and, with proper caulking they will never leak and be a good solid foundation for panels.
