Did you ever figure out the cause? I am having the exact same problems and it's very frustrating.

I'd agree with blue. I put in the grade eight kit but I used an old man emu steering stabilizer. Never had an issue. Make sure all of the bolts are tightened down to their torque spec. The control arms, bolts for the drop brackets, end links, and both track bar bolts. If its still squirrelly. Have an alignment done.

I would also check ball joints on steering issue and power steer pump arm bearing tight. You should also check your tone rings to make sure they are clean and not damaged, for ABS problem. Also, do the grade 8 upgrade!
