I would bring along larger sinkers in case there is any heavier surf. I typically throw out 3 oz, but also keep 4 oz and have had times when this wasn't enough to keep things put.
Do you have sand poles to stand your rods up in?
I try to check with local bait stores and see if they have live sand fleas as they work way better than frozen in my short but productive experience.
I also bring along my sandflea seive and after initial baiting up, dig my own fleas.
Other than that, something to sit on and maybe a good book and SPF and you are all set.
Good luck!! Post pics of what you catch.
