I have never bonefished the T&Cs but I do bonefish Cuba. Basically the same thing ..different spots, and of course different governents. Make sure you have your tidal charts ahead of time, print them up and pack them. I fish with a 9 wt. rod, large arbor reel, and salt water floating line and lots of backing. Do not use anything but saltwater flyline.... as "regular" flyline gets very limp and doesnt shoot very well. I used leader at about 12lb. Good sunglasses are a must to "hunt" bonefish, as seeing them is an art. This is why most people hire guildes, cause they cant see the darn things ..
Read this book: Fly Fishing for Bonefish by Chico Fernadez. This book has an excellent insites to the workings of this fish, and when and where it can be found, sited and fished.
You can research all the flys on the internet ... and if you dont ty... ebay is the spot to go and purchase. There are lots of serious tyers who love to do saltwater flys, all from the Florida Keys area.
I would highly suggest you purchase a good pair of boots, I purchased Bite Primal Flats. These boots are relatively inexpensive - below 90 bucks - and ensure you do not injure your feet while walking the beach or wading the flats. Remember, nothing is worse than a cut foot on a vacation .. you might as well rightoff all the money you invested.
