Thanks for the feedback, everybody! Having spent an arm and a leg on the gear I need all the reassurance I can get it was the right decision... 
How is the place for wide angle ?
Any signs of coral bleaching ?
Which dive sites you liked most ?
Any potencial for topside shots (landscape/wildlife ) ?
Which dive operator / guide you use ?
You did afternoon and night dives ?
Any shore dive ?
Jose,
1. There's a few scenic places, and you might come across a small school of jacks, the occasional turtle or barracuda, but mostly I'd say this is a macro location.
2. A little, but overall I'd say the reefs looked quite nice.
3. Cambaquiz Slope (harlequin ghost pipe, dragonet, frogfish, devil spine, etc), Viewpoint (pygmy seahorse, best place for "big stuff", sea hare, squat lobsters etc) and House Reef (denise pygmy seahorse, orangutan crab, leaf scorpionfish, lots of cowries).
4. Not much... There's a small lake, but don't bother spending time walking there. You can do stuff like this from the resort, basically:

5. We used Polaris and were very happy with them. They're the only resort with WIFI (if that matters to you), they've got good dive boats and most importantly excellent dive guides who really understand and cater to do photographers. We mostly got a guide of our own and were allowed to stay down as long as we wanted, which is really helpful when you have divers on the boat who run out of air after 45 minutes while you can stay down for 90 minutes...
6. Yes, we did three mandarin dives and one night dive. All quite nice, especially finding a baby clown frogfish during the mandarin dives (we harrassed the poor fellow on every single one of those...). The mandarin fish were almost more shy than normally, however.
7. We didn't do any shore dives, there's really no point, but I suppose if you absolutely must cram as much diving into a day as possible, you could wade to the House Reef, without a guide. Dives are normally 9 AM and 2 PM but they can also do one at 11:30 AM.
Hope that helps,
Tom
