I guess you're going to grad school at FSU after doing undergrad in upstate NY? Sounds familiar, I did the same thing about 20 years ago. Moving from upstate NY to north Fl is a big change!
Here's what I would do: take a few dives in the pool, get a little confidence back, then take AOW. I have heard that PADI designed AOW to immediately follow OW; probably their motivation is as much financial as it is pedagogical, but it does kind of make sense and I would not feel like you need more experience before taking it. It's not really an "advanced" course at all, it's just extra training and some minimal experience in different kinds of dives you're likely to encounter.
One other bit of advice, don't go night diving in any lakes around tallahassee unless you're interested in combining alligator wrestling with diving as a new "extreme" sport.
