Never fished that area, but if you're going some time during the summer they should be spawning. That means at any given point there will be a lot of them on the beaches. I always like to fish the beach at daybreak, casting parallel to the shore. It can take some getting used to. If you can find structure all the better. They will be within the first 10' (usually within 5') of shore, they call it the trough where the waves break. Baits vary a lot, anything from jerk baits to soft plastics worked SLOWLY along the bottom may work. They're visible if you really look, but they can be tough to see. You'll also find plenty along the mangrove banks in the back country near passes and such. Having never been to that area I don't know what you'll be working with as far as back country.
Use a 20-30 lb fluorocarbon leader tied to your main line of choice. Snook have a gill plate as sharp as a razor blade. Main line doesn't have to be anything heavy, 12lb is what I typically use.
