Most reputable shops that perform alignments also check the front end before doing the alignment - you probably didn't do any suspension damage but a good shop will make sure.

Have a look at the top of the strut tower to see if the backing plate held by the three bolts has moved at all from the bump - usually you can tell visually by the change in the plate's outline in the paint (or dirt). If you see it has shifted you can loosen the nuts and move it back to it's original location. Still get an alignment though.
