The text on the Cross References should be automatic so you should not need to run any batch command to refresh the references.
It didn't update at first but has now.
To go to the other end of a Wire you right click on the cross reference and select "View Related Items".
You can also hold down the shift key and click on the wire to perform the same action.
BTW - VeSys 2.0 v2010.1 now has a "Move End" action which allows wires to be disconnected and stretched to a new location as part of a single action.
