Yes, that would be fine.

No. A window may be both fullscreen *and* maximized, meaning that when
it leaves the fullscreen state it will be maximized. But fullscreen
has higher priority, and the two states are independent.

(At least, that's the only thing that makes sense to me.)

For Xrandr you should clearly resize all fullscreen windows to 
the new root window size. For VidMode, it probably makes sense to make
them track the monitor viewport. For Xinerama, you should fullscreen
to only one Xinerama head.

i.e. the short answer is "do your very best to make the window exactly
match the size of the monitor"
