if you really want this have it poured when they do the walls.

1) 1" is not thick at all when looking at over all weight, but if you put a cross brace or 2 down the middle, it will help.....

2) Venting will help a lot, just keep air temp in mind as well.

3)Depends on how you go about doing it. I would use good flow across the bottom and just run suction lines for sand filter inlets. For water return, I'd run one into a bio tower set up, and one right into the tank.... with valves to control flow to each.
Aquatic Eco has some great package deals on pumps with sandfilters for pools of this size. Look into those.
