On my kodiak based gulfstream, I had found a console at Autozone that fit pretty good and had a decent amount of space. It was tough to find something that had space for storage, yet allows access to the back easy. The other option is Tuffy Consoles sells a narrow (8"?) console that should fit there pretty good!
As far as switched power and what not, I got all my power from the fusebox itself. For the in dash double din DVD player, I didnt used switched power, I used constant hot and put a rocker switch in the dash. That way it can be turned on with the key off.
