Yes, Hep A. This is actually recommend even in the states nowadays.
I also have gotten typhoid, which is good for more 3rd world countries and probably not needed for Bonaire but a very good idea for Mexico. I usually go by the CDC website. I think I have the typhoid and yellow fever shots for my Africa or Central America trips.
Tetanus is important when shore diving, since its easy to cut hands and feet.
Use bug spray as Dengue is indigenous to Bonaire. ( its also become indigenous to the Florida Keys lately,BTW). You really don't want to get Dengue. The no-see-ums can be bad,to and I've had a miserable trip to a few countries when bitten by no-see-ums. ( Nicauragua specifically).
I love Cactus Juice, it has sunscreen and bug repellent and I've had it work well in Bonaire. Other people claim it doesn't work. It was recommended to me by a woman who has a house in Honduras and I've never had a problem with it. Maybe others don't apply it thickly enough or frequently enough? I find it works great!
Of course flu shot. When traveling, everybody on the planes is sick. You sure don't want to be sick during or after your trip.
