Not remove and restart. Stop, then remove (in the dlimits directory,
you're right), and then start. The order matters.

Yes, that is the idea. It's the amount of virtual space the
guest has.

If it still isn't accurate after doing the above, try
vdu --space --inodes --xid <guest> /vservers/<guest>
If that doesn't show what you expect, you will need to
retag your guest.
