Nice one Ian ... as usual you have answered the Qs I asked and the detail I did not ....
Just clarifying A4. Are we saying I can enable this gratis on the LTM i.e. it is paid for under the LTM license and just needs activating? And GTM all I need to do is activate the options (caching / Express) under the profile and I have no ancillary licensing REQs over and above GTM license. (struggling to see the point of this as a separate license entity TBH if this is true ... )

Each purchased BigIP module or add-on turns on a set of flags in the license file. Those flags are what are actually checked, and any given flag could potentially be turned on through more than one SKU. This also changes with versions, and the good-better-best licensing model also changed the way a lot of this worked.
With VCMP, the host is licensed, and the guests receive a copy of the license, so are able to enable any modules that the host is licensed for. The idea is that you could have a GTM vcmp guest, and a few LTM guests, and one with APM, or whatever combination the host is licensed for.
I'm 90% certain that the SKUs we sell for "GTM" (which is now sold as BigIP DNS) all enable the LTM DNS feature flags, but if you want to be absolutely sure, you could talk to your account manager, or open a support ticket, as it would depend on the actual SKUs that you have purchased.
