Well you certainly should get some good ideas from the posts in this thread so far.  

For a single hurricane event, you're probably more prepared than most.  Having lived through one direct hit of a hurricane (TX) and recently interviewed a bunch of folks in FL, I would like to make a couple comments.  

After a hurricane event assumming utilities off for up a to a week (what happened to us in TX), the number one enemy that nature throws at you is heat.  Combating heat is one of the biggest problems and most costly to combat.  Leaving windows open for example has security issues, everything that goes in the fridge spoils, and its just downright miserable especially at bed time.  

I'm not being condescending but if I may make a suggestion, I'd focus my planning just tad more to handling that event rather than something more catastrophic and shift a little more in that direction than the live off the land direction.  We have a saying here on the forum.

Prepare for the most likely scenario first and the least likely scenario last!

FL is probably the only state in the US where I would recommend everyone have generator even if its a very small one just capable of running refridgerators or a window AC unit and/or a fan.  As you consider this option keep two things in mind. The number one limitation of a generator isn't size but how much fuel you can keep.  Last hurricane season FL residence thanks to FEMA assistance had a record number of gens, however they also had a record number of gens not running.  Some people due to their situation simply couldn't store fuel while others didn't realize their cars were full of it.  If you have two cars a second car is an excellent source of gas.  The other thing is gens don't have run 24/7 to keep a fridge or freezer cold.  Still being able to run your AC a couple hours before bed is a pretty big deal to most folks in FL.  

Barring not being able to own a genny and still a good idea even if you do is having ice.  Ice costs near nothing.  Any empty space in a freezer can be filled with plastic bottles filled with water.  Years ago during my hurricane event, honestly I got lucky.  I was so into  an outdoor recreational activities that I was already freezing all kinds of ice for coolers.  It was less hassle than stopping to buy ice everytime I wanted to go fishing. Just before the hit I added more.  It bought me just enough time to consume my refriderator food before I started on my canned/dry food.

After a huricane, I wouldn't suggest filtering water.  Huricanes are rain events and the runoff from the storm/flooding will have permiated every creek or body of water contaiminating it with primarily ashpault runoff and often industrial plant runoff.  This is some nasty stuff with a variety of chemicals that may not kill you now but could 20 years from now some of these in parts per million or billion. Most filters will be quickly overwhelmed by this amount of chemicals.  That being said, the number one use of water isn't consumption but flushing your toilet.  Identify the closest water source and have containers to transport it.  (BTW, as a personal note.  I had people lined out my door after they learned I had a flushing toilet.)

Another thing I consider very important is knowing what is going on.  This helps you establish timing on all kinds of stuff.  Radios are a great source but one has to keep in mind what is being said is the official line more often than not.  A very small battery operated TV is a big plus since you can see as well as hear.  More localized a small handheld battery operated scanner can give a heck of alot of information even if it is just the fire department, EMS, and most importantly listening to the utlity frequencies.  

Lighting becomes a paticularly hard issue for FL residence.  Anything that puts out heat isn't desirable.  Though personally a  big fan of candles, lanterns, and oil lamps in FL, I would lean way heavy battery operated LED lights.  

Keep in mind, It isn't he who barely survives SHTF that wins but he who barely notices it.  It would be kind of nice after a hurricane to have some time off, be at home with the familly, listening to the radio, reading a good book, watching a ballgame, and all in airconditioning.  I know many folks in FL that do just that.
