That is up to you, I think if your mains are far enough away from the sides of the TV to provide ample channel seperation then 2 bookshelf speakers on either side should work fine. I would try to make sure they are mounted about midline of the screen to ensure a centered sound. The single center is always there as a back up plan as we know it pretty much works no matter what.
