Fred,
pick up a copy of
Diving Guide to Underwater Florida by Ned Deloach. It's pretty much got them all covered. It's well worth the $15 bucks. Make sure to get th 11th edition (with the Grouper on the cover) to get the latest version. You can pick it up at Books a Million or Amazon.
also check out The Florida section of Shordiving.com

Crystal Pier Pilings in Destin used to be a good dive, but SeaYoda and I dove it in May and it appears the recent years storms have dumped a lot of sand there and reduced them depth from 10-20 feet to 5 to 10 feet.
Sea Yoda and GulfGulper have also dove the bridge pilings of hwy 98 between Destin and Okalossa island. (watch for boats).
Bugman and crew dive the
Navarre pier pilings on Okaloosa island also. They also often hit
Cypress Springs, which you'd need to rent a canoe to get to.

Over in P'Cola, people dive the Ft Pickens jetties, but right now the park is closed to autos/cars due to storm damage.
that should keep your mouse clicking for a while.
