Actually, I was poking around at it some more and, after reworking the layer inherits and changing the pixel values by magnitudes (1000's then 100's then 10's) I have it roughly dialed in.
I can always fiddle around with it manually some more later, but thank you for the help!
Never did find those global settings though... /shrug
Manual is fine, plus I can learn more about settings I didn't know about.
Thank you!
