Ted,Corners are the most effective locations for dealing with bass absorption. You can get bass absorption elsewhere in the room but you will either have to settle for less absorption using the same amount of bass traps, or use more bass traps to get the same effect. Bass traps have a habit of taking up floor space since it's hard to absorb low frequencies with something that has a small footprint, and large footprint things seem to be less obtrusive sitting in corners where you only see 2 of their faces rather than 3 if they're further along a wall or 4 if they're free standing in the room.
Furniture and even bookcases with lots of books won't give you bass absorption. Books do make reasonable absorbers but probably more in the mid to high frequency range. While people also talk about books as diffusors, and they do diffuse sound to a degree, diffusion at bass frequencies requires quite physically wide and deep diffusors due to the long wavelengths of bass frequencies. While bass diffusion would be a plus and getting that in corners would be better than leaving the corners bare, it would still not be as effective as bass absorption for treating low frequency room problems and you definitely won't get any useful amount of bass diffusion from the kind of furniture you mention (or from any furniture I'm aware of, for that matter).
If you can possible place bass traps in the corners, do so. They will work more effectively and be less of a visual issue there. Also, bass traps do work better if they extend from floor to ceiling. It's not only that extending them full room height gives more surface area and overall volume for absorption. The simple fact is that you can hear differences betweeen the treated area of the corner and the untreated if you don't go full height and the sonic benefits of a fully treated corner are much better than those obtained when your treatments only extend to part of the room height.
