rotating without child/parent

Hi I am haveing some trouble with rotating a few objects. I imported them off the web becuase I don't have the right software and they are facing the wrong way. I know how to rotate them to the correct direction using parent/child, but I need them to follow another object using the smoothfollow script. How do I rotate the objects without using a different software of parent/child?

Maybe you can encapsulate your object into a parent with the right rotation and then apply the smooothfollow to the parent ?
