You really want to set the ride height by determining how far up the lower suspension mount is threaded on to the center threaded strut section.
Preload will absolutely effect ride height, how do you think KW/RCE's work?

Preload does not have any effect on spring rate. Preload is simply stored energy. A 400lb spring with 1" of preload still has an effective rate of 400lb.
