I would not be so worried about the seat height. As long as you can get a foot down to hold it up at a red light.
I'm 5'6" with a 30" inseam, I just started riding a 02' ZX9R with a saddle height of about 32.5". The Ninja is a bit hard to back up on a hill and I'm only able to get flat footed when I put one leg down. But, the BIG plus is the cockpit fit. When I'm up on the bike my short legs are a perfect tuck from peg to tank.
You spend 99% of your time in the cockpit, that's the fit you really want to be comfortable.
