I realize that it's been said many times already in this thread, but I too want to urge you to forget the camera for now. I tell people to wait until you have at least 100 dives under your belt before taking a camera down. You're doing a disservice to both yourself and the reef.
Not only will you miss a lot, it's also a safety issue. Your life is literally in your hands when you're diving, and with only a few dives under your belt, you're still learning your equipment and the new environment around you. It's simply not worth trying to get pictures when you have so much new stuff going on.
Imagine if you were helping a brand new driver learn to drive, and they wanted to eat their lunch while you're giving instructions. Would you let them? This is the same situation - nobody here is trying to challenge your intelligence - we're just trying to make sure you're setup for success.
Underwater photography is challenging in its own right. There's no need to add in the challenge of learning a new environment.
Also note that $1000 won't get you very far in uw photography, unfortunately. If you're really, really determined to do underwater photography, I suggest a) waiting until you've done at least 10 dives in Bonaire. If that's 5 dives/day for 2 days, then fine - just get some experience under your belt. Then b) rent a camera from one of the shops on Bonaire. Check out Bonphoto or Fisheye. You can rent an uw setup for far cheaper than you can buy and have none of the risk of flooding.
Be safe and have fun!
