Yes you can go finer, but it's the balance of contrast/brightness and fineness that makes the difference.

There may be some variations in Grit quality but using #400 followed by #600 gives screens that are superior to the standard Graflex screens and many other commercial screens.

No because the grain of the ground glass will be an issue.
