Print size, but make sure that this is what you want - if you set the
ppi value to 8 for a 8 pixel image, you do this because you want it to

You can index the image to a 1-bit b/w palette, but that won't matter
much until you export. It should also be ok to just paint in black and
white and worry about that later.

Sure. Check out the View and the Image menus, you can switch the grid
display and behavior there and set it up for your image.
