Not certain if it's helpful, but have you cleaned the rollers? I wish I could help but when I had mine it seemed fine and I don't recall having an issue like this for what it's worth? Good luck!
In this photo, there's what looks to me like a light leak. It's that white streak that looks like someone took an eraser to the print. This was the third shot I took and all three had this in the same spot.Were all three shots in the same position/lighting? It too could be pressure marks from handling. Light leaks have a tendency to change in intensity proportionally to the lighting and the source with respect to the camera. The most likely source of a light leak in the instant film backs is the darkslide slot. The felt wears and gets compressed allowing light to enter when the darkslide is removed.
3. The leaf shutters in the lens are Seiko shutters. They are not difficult to service if one is experienced in shutter repair. The only reason I will not offer to service them for you is that I do not have the special tools needed to remove the lens elements to access the shutter.
4. Although I have never used them http://www.ictcamera.com/ is a company I would try if I was not able to do it myself. Dead Link Removed may be a good choice also.
If you can't find anyone to CLA it, I can at least replace the light seals for you if you wish.
It would be seals for one 120 back, both sides of the rotating back and the mirror dampers.
Re your 1st issue - are you sure you're pulling the Fuji evenly through the NPC pack?(post-exposure) -that tends to have quite an effect on things.
Its also something I have seen more on the all-plastic back(Lane) I have -results similar, with photo printed to one side, and a dark blob on the other.
On the second, I just checked my Polaroid backs and neither seem to have the right amount of foam, the lane doesn't have any at all. And I havent experienced any light streaking - on portraits, studio/outdoor portraits, landscapes and indoor low light shots as well. Maybe the problem is elsewhere?

It's normal for only a portion of the print to be exposed on an RB back.
1. empty couch shot-smudges on the wall are from handling the film or dirty rollers. Instant film is very sensitive to pressure, could be from loading the camera back.

Thanks, shutterfinger. That's a good point. On that FP-3000B pack, I was a little distracted (ironically by watching a video on how to load the Polaroid back) so it's very possible I mishandled the pack while putting it in. I was more careful with the second pack, and that's probably why it didn't happen on that pack.
All three shots were in the same position (on tripod) and taken in succession with slight changes to settings due to clouds moving in and out. From my best guess, the direction seems more to be on the opposite side of the dark slide, so the side where the film comes out. I'm wondering if that's the cause.
This is another test I did. Much more prominent in this one, but it was a much brighter day so that might be the cause.
Thanks for all the advice, everyone. I'm really looking forward to using this once I get through all the little issues.
Remove the lens and operate the body so that the mirror is up. Now attach the film holder and remove the darkslide, use an empty film pack if necessary fill the void in the back so it is like it will be when loaded with film. Now go into a totally dark room and set a mini mag flashlight to spot at 2 inches.
Place the flashlight in from the lens opening and observe the back. Any hint of light coming out of any opening is a light leak. Next looking through the lens opening put the light against the film exit, darkslide slot, back hinge, then around the perimeter of the back and adapter mounting points to the camera body.
Light leaks will be anything from dull yellow to bright white.
Oh yes, the light leak could be coming from the seal around the mirror so be sure to check the finder as you shine the flashlight around the inside of the body.
