What I can tell you is that (1) lowering the car will nose the pinion in the downward direction, and (2) with polyurethane or spherical control arm bushings of any sort you don't need as much pinion angle even at stock height. Basically, both of these effects call for PA adjustment.
What I can't tell you is how swapping in a one-piece D/S affects PA requirements. If it needs less PA than the OE two-piece, that'll be a third effect asking for adjustment. But if it typically needs more PA, you might not need to do anything.
Worst case, install everything except the adjustable UCA and see if you have any driveline vibration, and only "fix" it if you get any. This would be good enough approach for satisfying most normal street driving at reasonably normal speeds, but might not be optimum for drag racing purposes.
