The Plaza will give you a key for your locker for the week. You don't need a combination lock. Tanks are right outside the lockers at the dive shop and also by the beach for shore diving. They are all air. Nitrox you will have to set up separately. Yes, there are safes in the room.
By the way I was at Plaza Resort Bonaire two weeks ago and the water temp was 78 degrees -- much cooler than usual. I've been twice before in February and the water then was around 80.
I always travel with collared short sleeve shirts. That and a pair of shorts will get you about anywhere in Bonaire. Long pants are nice if you're outside to avoid the bugs, however. Take some DEET as mentioned above.
I've also never had a problem with theft. Just leave the windows down and the doors unlocked.
