Success!! Well, success so far.
I drove it to NTB to get an alignment and everything was in spec
except for the toe (of course). The camber was unchanged, but the big thing is that the caster was nearly spot on at 6.5 and 6.7 degrees. I would've preferred 6, but that's good enough for me. I can always lengthen the uppers to reduce the caster a bit. Easy cheesy. And best as they could tell with their equipment the axle was square relative to the chassis! I'm really excited. After all this work, it's scary to get that first alignment. You don't know if the specs are way off or if you'll have all the adjustment range you'll need, etc. This was a huge milestone for me.
It drives great! Granted, I've only done the front suspension so far, but it rides so much nicer than before. I'm really encouraged that after the rear is done this thing is going to feel like a Cadillac compared to the way it was.
I also managed to hit some really big, ugly speed bumps and everything felt (and still looks) very, very solid.
I don't know if I'll get chance to test it on the RTI ramp or offroad before the Jeep Jamboree next weekend, but so far things are falling into place nicely.
