Any Gem can have as many eyes as they want because their bodies are illusion. Maybe Sapphire does have one eye, maybe she doesn't. Maybe Garnet just chooses to have a third eye and uses that one eye for her future vision sho she can stil be aware of the things happening in the present with her two other eyes.

I doubt they wouldn't have time to change their outfits because they can change their outfits whenever they want. I think thye just chose not to wear the insignia of the Crystal Gems because they don't plan on representing the Crystal gems when they're apart because they never want to be apart.
