Hello William, welcome to the family!
Your setup does sound like a pretty safe setup...Granted I don't really know your room dimensions or much else about your room. Our 533 center works great for most medium to large sized rooms, as well as the 532 books. They have a sweet, open midrange, and work well in a lot of different rooms whilst still having the flexibility to be mounted on your walls, ceilings, stands...etc.
If you want to dive a bit deeper into it you could list your room specs or some pictures, but hey, the speakers are already on the way to you. I say grab em, set em up, rock out for a few hours and let us know what you think!
Cheers,
David Bolt
