Baranowski, I'm getting the sense that you really want floor standing speakers for surrounds. If I'm getting that sense correctly, then go for it. There's no question that deeper bass will be more uniform in the room, crossover will be far lower, etc. etc. There's a big difference with quality full-range speakers vs. bookshelves in a setup. So I say go for it and see how you like it.
As a side-note, Toole's book is great. If you ever want some geeky reading, that's the book to grab.
