not necessarily. could just be from pevious work on the car, hitting something, a number of things really. doesn't mean any parts are bad. have a shop you know and trust do the alignment, and usually they will check stuff like your tie rod ends and such to see if you need new ones. and your power steering pump wont ffect the alignment, all it will do is if it starts putting out lower than needed pressure it when whine when you turn like it is out of fluid. it may be a little more difficult to turn as well.
