1. I believe imagaing is the "invisible" focal point where the music produced from a pair of loudspeakers meet in the middle. It could also be a center point where music from a surround sound system meet as well. It's where the speakers disappear and the sound is in the middle of the room so to speak. Of course it's in your ears and head where it ends up !!
2. Soundstage has more to do with how close you feel you are to the music (from the stage so to speak).
3. Just my humble opinion but I would minimize large sound absorbring or sound reflecting solid objects between loudspeakers. Keep the area relatively open so the sound is free to image properly. Keeping the speakers forward of the objects will certainly help somewhat. Just my opinion.
There's much to consider when setting up a listening room for your sound system. I believe the room set up and arrangement is as equally important as the audio system itself. If your room is too alive for example, you need to add bass traps and absorbing materials such as upholstery, carpeting, drapes. If it's too dead, you need to open it up and remove these types of items.
