Caster is way more important, than pinion angle

Yup, the front drive shaft is long enough that minor differences in pinion angle are negligible. I'd just line it up with the transfer case yoke in this case. Low caster angle will give you the 'jeep wanders all over the road' effect so that's a pretty big deal.
