Any real gains from going 1inch vs. .75 inch MDF? I'm using 1 inch now but I want to cut down on weight. Would .75 really make a huge difference in sound?

No. There's no reason to use 1". 3/4" with a double baffle and proper bracing is plenty.

It really depends on the size of the cabinet. But even a large cabinet can be braced well if built out of 3/4" material. But, if you're using 3/4", be sure and laminate the baffle with two sheets. Even with one inch material, I'd want to laminate the baffle with " so it would be 1" thick.

Probably around 3.0 gross. I will try .75 next time to save on some weight.

On an unrelated note, should I try birch or some other type of wood?

Birch will greatly reduce weight and allow you to increase thickness/layers and still reduce weight.

I also heard that birch sounds a lot better. I think my next box will definitely be birch. Is birch any weaker than regular MDF? Would it handle a HDC312 on 1600RMS?

There's no reason to do 1" if properly braced. If it's just that HDC3 then ya you will be fine with .75". I think I've only ever done 1" like twice in the past 3 years designing for people.
