With mic location, IMO it is key to have the mic a decent amount away from the cab, and not directly on-axis. That gives you a pretty good feel for the general tone of the rig, again, for that player. The thing you don't want to do is put the mic very close to the speaker, which is not really representative of the sort of 'live performance' of the cab.
Whatever you're doing it sounds great!
From a listener's perspective, the setup on this clip is amazing.

Playing that through studio monitors I can clearly hear everything that you're talking about. Super helpful.
These are nice too, although they introduce a bit of room sound into the equation.

All are high quality and very helpful. I like the first room/setup best.
