Here's a few things I would add.
If you have a grill it would be a good idea to stock up on charcoal/gas. We have a gas grill with a side burner and we have crawfish boilers. (Propane burners)They can be used to boil water if needed.
If you have an electric water heater you will really appreciate taking a warm bath.
We went without power for 8 days when hurricane Andrew hit Morgan City.
Disposable cups/ paper plates.
A battery operated tv is a good thing to have. You can pick them up pretty cheap now.
Make sure your homeowners insurance papers (and any other important papers) are handy and in a safe place. Preferably, in something sealed so they can't get wet.
Most of all stay safe.
