Camber:Caster:Toe,,, and my self steering NX

Okay I have a “Self Steering” NX
I Installed new coil over kit, kept the factory styled front struts and replaced rears with some KYB’s
I think the car is to low cause the front strut botoms out crossing the smallest of bumps, then while driving and holding the wheels straight this thing will walk left to right, i mean a few feet at a time with out moving the steering wheel at all.
So My question is should I replace the front struts with ones that have a shorter throw, or travel, and if so what do you reccomend, its a 93 nx1600 so parts are not that easy to find at times.
Also I know im outta toe in the front for certain, along with camber, which brings me to the rear where i have a serious caster issue, How do you adjust that? I see absolutly no adjustment for caster??
I dont want to take it to get aligned untill i find a good ride height, and replace any parts that you guys suggest…
-Other than the car, I like this little rusty ricer-
