Struts part 2?
Absolutely no need to. Struts do not change ride height or move suspension geometry.
If you had changed to lowering springs or new exact replacements you should have it re-aligned.
Struts part 2?
have them do a four wheel alignment
By changing the front struts the rear wheel alignment will not change however since you fixing up the car it would be a good idea to have a 4 wheel alignment done since you need to have the front alignment checked anyway after replacing struts on the front. Your car will drive straight and give you maximum life from your tires that way.
