I don't think there is any issue with allowing the HV supply to run with no load. In normal operation with CRT connected, if you turn the brightness down to the point the picture is black, there is no load on the HV. I'm sure none of us would think of turning the brightness down as something that would harm a set, so I would not be concerned about running the set with the HV active, but disconnected from the picture tube.
Running it into a HV probe can be nice simply to keep an eye on things, but it's not necessary.
A glass jar as an insulator is good. Usually I simply prop the lead in a manner that the end is not close to anything, but it is a bit precarious that way.
