I have little to say about the pressure plate, except that I'd be unhappy. If the manufacturer can't get the balance right, I'd have preferred to ship it back to them and get a different one. Maybe that's why I don't own a manual-transmission vehicle any more--too picky.
I wouldn't be overly concerned about the crankshaft. Removing weight like they did might cause some minor rocking-couple out-of-balance, but the crank has so much rocking-couple designed-in already; and I don't have a way to know if what they did would make it worse...or better.
Why would you "order a factory external-balance flywheel" if you own an aftermarket flywheel that balances properly? Seems to me like you're paying extra to put a bomb under the floorboards. I hope you have a scatter shield. (I'm assuming the aftermarket flywheel is steel and not cast-iron. Maybe I'm wrong.)
