should i switch left to be right & right to be left and have the 5.25" driver point INWARD?
There is no correct way. It is a matter of choice. Do it both ways and choose the option you prefer. Their performance depends on the room acoustics and personal pereference. You may like it one way in your room and I may like diferently in my room. Ultimately, the rear surrounds do not make that much of a difference.

You have a more serious problem with Definitive Technology Super Tower front speakers and their built-in subwoofers. You can position them so that the subwoofers are facing each other or you can position them with the built-in subwoofers facing outward. In their manual, Def Tech talks about the different sound that you may hear, but leave it up to the customer. I have my speakers facing inward. In the case of subwoofers, the interaction with the room boundaries is more of a serious problem.
