Lots of hooks. I'd look into some treble hooks as well.
My haven't used them much in the gulf, but hurricane or spider sinkers are useful if the current is rough. A 1oz spider can hold like a 4oz+ pyramid.
Rod holders, camera, beach cart, pocket knife, de-hooker, tape measure are all other helpful items. Don't show up without a camera, you will regret it when you catch a monster.
