You have to think in terms of supporting the weight of the car.
Sure, adding 6+ degrees of positive caster increases the steering effort. But the amount of force you need to add to notice a change in the steering effort is fairly small, especially when you consider that the control arms are carrying the weight of the car (especially the lower one). So adding 10 lbs of resistance to the steering effort might seem like a big deal when you're trying to turn the steering wheel, but for the suspension that's carrying say, 800 lbs on one of the front corners? Not significant at all.
The same place you always measure it, on
every car, regardless of how much caster it does or doesn't have. Doesn't matter if the caster is -1° or +10°.
Nope. The toe
measurement is independent of pretty much everything regarding suspension geometry. If you're measuring it yourself, it's just the difference in the distance between the front tires taken at the front of the contact patch and the rear of the contact patch.
If you're measuring it on an alignment rack, it's just the angle the wheel makes from the longitudinal axis of the car.

Adjusting the caster and camber will change the toe, but, they don't have anything to do with actually measuring it for a static alignment.
