Remember that xserver is the machine where the graphical output will be 
created. Yes, if the host has an xserver already then it's smart to use the 
xserver of the host and connect it to xclient applications running in the vm.

It am not sure. I recommend to learn the application "screen", which gives you 
virtual consoles in the vm that can be detached. The shell will be active where 
it was and you can connect to it later at the same point and continue. Running 
programms will continue to run in a detached screen. A normal login shell will 
terminate if you logout. In "screen" you can open more shells, i tried 15 so 
far, not sure where the limit is. But i am sure it don't want to miss screen.

Yes. The vm is like a virtual pc in the network.

Yes. But it can be tricky to get it running. rtfm recommended strongly.

It depends to your dos programs if that is required. i would prefer dosbox 
before the dos vm. But thats personal taste.
