All of the above is good advice. About the only thing nobody mentioned yet is what my buddy Chappy calls a "tourist rig" . A popping cork or cajun thunder with a 1/8 oz jighead about 18" to 24" below it. (what he often forgets to mention is that some of his biggest trout came on a so called tourist rig
Hang a mud minnow or a live shrimp on that, cast it near an oyster bar with a bit of tide moving through it and hang on. Works great with a 3" gulp shrimp too. Your bass gear is perfect for most inshore work as long as you rinse it when you're done.
The other thing nobody mentioned is that you need a way to stop the boat. A Stake Out Pole (SOP) is what most folk use as most places inshore are MUCH less that 8' deep, or have a shallow spot to stake out on within casting distance. You can also back your bum up into the grass, but a SOP with an anchor trolley gives you a lot more flexibility. Search "SOP" and "anchor trolley" on this site to learn waaaaay more than you want to know.
Also try to pack as little gear as possible. That means bringing what you need and not the giant Plano box. There's just not enuf real estate available. And WEAR your pfd! As important, HAVE FUN!
