This makes it easier on your CV and also helps alittle with the alignment.

Dropping the front diff housing has absolutely no affect upon the alignment.

Most likely, you will have to crank the front end down a bit, plus moving the ball joints, to get it closer to spec. If you are that cranked, you are probably sitting on the droop stops anyway and need to drop it a little so it might handle a bit better on the road.

Good Luck,
