Makes sense to me. Set the car up as your going to run. Measuring everything unhooked other than toe and steering doesn't make sense to me. The tyres you use change in diameter between brands and wear, so ride height will alter (and camber also, but minor) which you need to compensate for. And then droop needs to be altered to suit!
If nothing else, I think ride height should definitely be set with the tyres you plan to run and droop should be set with everything connected (wheels off obviously!)
I'm pretty novice with TC and don't even have a great setup station. I use (very accurate) verniers, blocks and height gauges, a 4 sided (well eight technically) camber gauge and a bit of nouse. Setup wheels would be nice for more accurate camber, but the car runs true, has good traction and stability and I'm not noticing drastic wear on the tyres.
Even if I got, say, set up wheels, I would still check camber with the tyres on afterwards.
I also have more important things to work on other than chasing set up!
