In the sequel movie, you see Zach and AERIS together (they were an item, after all). It was a glimpse of their spirits. Even towards the end of FF7 game, you can witness Aeris's ghost at the Midgar Slums church.
As for the Phoenix down thing? I've always figured that 0HP was closer to being knocked unconscious, or brink of death. Sephiroth put her down to -10, which meant she was straight up dead, and no phoenix down would help.
