Lots of the guys I went with fished ganged hooks but I found single hooks (6/0-7/0) worked just as good. The fish there don't muck around. TLD 15 is a good choice, spin reels don't hold enough line for the whole day. I used an old Alvey which was the best. Expect lots of bust offs. I prefered dory fishing rather than the main boat. Main rig I used was ... no trace, sinker above the hook, found that way replacing terminal tackle was quick and easy. Night fishing off the back deck can also be good. I fished near to fixed drag, if you try and play them you'll get busted off on the reef.
Don't put you hand over the side to pick up fish, the sharks are not far behind.
Have a great time!
