in zbrush you can extract subtools, or hide points as far as I remember.

Also for the holes you can make some parts different polygroup and then do split groops and you will end up with a hole on that spot. This is if you would like to do it all in zbrush. Doing it this way you might end up having some triangles but this is not so bad sometimes.
