Cool pics! And thanks for the backfill on your "adventure"... even if it is a job. 
As far as your cross-articulation error, I would bet anything that it's a calibration issue. Calibrating only two wheels is definitely a no-no. If you spend 45 mins or so and do the full calibration, I think that error will go away.
I actually experienced a cross-articulation fault when I used adjustable sensor rods and tried to make them all different heights. Basically, I wanted all of my calibration values to be the same (in the low range of what is possible... around 150-160). Unfortunately, the car did NOT like that and despite calibrating the suspension multiple times, I would random get that fault and it would drop me to the bump stops. I finally just made all the rods the same length, so now my calibration values are all over the place, but the car is happy... and calibrated... and fault free (other than my damn parking sensor).
BTW: ZF website says "Cummings Rocky Mountain" in Avondale is the closest ZF service shop to you. Don't know the first thing about them since I'm on the east coast.
Just out of curiosity, how many miles on the tranny? Has the fluid ever been changed? I haven't heard of very many issues with these transmissions and am just curious.
