I think I am going to give up on the stepper motor design and stick with DC voltage controlled for now. Most research I have done seems to indicate it will work well. Also look at

For accurate polar alignment, I think I can use a compass and an inclinometer app to set elevation = to latitude. Saves fiddling trying to line up with a non existent point in the sky.
