Hi, Rico!
Great to see you are working on and improving the NAF!
Ride Height - I would adjust it to where you think it looks good, but that assumes that your suspension curves are resulting in little to no change in caster/camber/toe through out the range of travel. Hopefully, someone with some knowledge of NAF suspension geometry can guide you.
Shocks/Spring Selection: I would contact a company like Spax or QA1 and speak with their technical people if you are looking for specific ride/performance characteristics.
