How to adjust ride height?

There’s a reason the FSM says they need to be tightened at ride height. It’s not just on install, it’s any time the height is substantially changed. Otherwise you run the risk of tearing the rubber LCA bushings. All the LCA motion is flex in the factory rubber LCA bushings. If they’re not torqued middle of range, they run out of flex.
Yes, but if the car has been lowered, either through torsion bar adjustment, or especially wear, then that means no one loosened the pivot nuts to begin with and you're simply returning them to "about" their original position. I've always found it pretty much moot point anyway. Never had any problem with it. To each their own.
