Should take one.
But I think you need about 400gph.

None really.

No.

 That seems like it would destroy non-glass diffusers

SS is pretty tough, it's used for Ozone and other strong
oxidizers.
I'd use the cheap disc, 2 of them and a V shaped flow pattern
that fits the 92 gal corner tank surface area.
That would spray the mist under the plants and to the front of
the tank.

If you used black CO2 tubing etc and have a back background,
then you can hide the lines in the rear corner where the glass
meets.

If you use 2 disc, use two needle valves. One for each disc.

Well, I suppose you can do both.
A little redundant but if you are mist happy, go for it.

Well, I think you'll need a good size pump flow rate,
300-400gph, the Magnum 350 might do.
