I must echo everything that Wes said.
The shark gallery dive is a must do! You need to bring nothing as their equipment is very good. But I would always bring my own mask, flippers & wet suit.
re: drift diving. I do not recall that being a problem. The current is not bad in FP.
I do recall my dive in Cozumel shortly after getting my cert. It may have been my 3rd or so dive. The current was wicked. A wee bit scary, but a hoot! & as Lisa correctly said, my bouyancy skills left something to be desired. I sure gave my BCD a workout that day!
Enjoy! Doug
