Sorry, I don't know about any Moorea diving either, but I did dive with Eleuthera Plongee
http://www.dive-tahiti.com/index.php.en several years ago (scroll down the pages - the website's not too good as it appears nothing has popped up but all the info is at the bottom!). It was a good days diving and I felt very comfortable with them, not rushed and not out of my personal depths. I was however the only English speaking person on the boat - no issues, I just got my own private briefing!!
