Is there a initial pre/post-dive checklist that I should follow?
Clean the O ring before closing the case - this forms the airtight seal. I did this the night before the dive in my apartment.
I didn't do anything post-dive other than rinse the case in fresh water, sometimes I opened the case once the days diving was done to review the shots on the way home.
Should I purchase spare parts? If so, what parts wear out soonest?
Spare O rings would be useful, not that I got any.
Somebody told me about something called a "Leek Detector" Has anybody used this? How does it work?
Not heard of it.
If the housing is defective for any reason, do I have a chance at all of getting a refund of the housing AND the camera???
No. I read the warrantee on this and they won't refund the cost of the camera lost.

I am very happy with some of the shots I got in Malta, I'll update the thread with a link later in the week but briefly - don't bother with the night-flash ever. The extended exposure always blurred my shots.
Macro with/without flash, and Auto without flash produced some fantastic results (IMO).
