Cheeze, I got the seats and sofa-bed from http://www.discountvantruck.com. They took a lot longer to get than I expected (3 months!)since they are suddenly very busy.
The TV bracket I used was pretty heavy duty from Best-Buy, but if I had to do it again, I would probably start with the one available from Campers-World as it's more likely designed for road use. I did add an additional custom-made padded bracket below the TV where the TV parks during travel, so there's no vibration or movement.
The lighting is wired into the 12V coach lights below the overhead cabinets. If you remove the light assembly, you easily access the wire-nutted wiring for those lights. I just connected to that connection on each side and added a rocker switch to separately turn the rope lights on. The lights ordered were "LED- 12v 6'6" Warm White Rope Light package" from CBConcept.com.
They provide a nice warm indirect lighting that is way better than the glaring stock lights (which are still there, if needed). Below is a poor picture, but gives some idea how the lighting looks.

below is a pic of the back of the oak valence I added with the rope lights attached prior to mounting the valence on the bottom of the cabinet.
