I sent the housing back to Backscatter after I got home, and they were super helpful. Sean was able to reproduce my problems. It turns out 3 out of 4 of my problems were traced to the screw that mounts the camera on the tray not being turned tight enough. I was only turning the screw to finger tight. Nauticam is saying it should be 1/8 turn past that. I waited until I got official word back before posting here. So for all the new owners of the Nauticam D7000 housing, make sure the tray is on tight and not rotating if you experience any problems with your buttons.
The last problem had to do with the Live View level. I was having problem activating LV reliably. During my trip I "fixed" it by taping a band-aid on the level to help push the lever on the body more. Word is Nauticam is making a new part for that function. Maybe that's the reason some of your orders are delayed. They're probably waiting for that part before shipping more housings.
Overall, I think it is a great housing. I can't wait to get it back next week for some more dives. Hope this info will save some time and headaches on your first trip out with the new housing.
Cheers,

PS. Almost forgot I had 1 more issue early on. I was using my Sig 17-70 with a pretty stiff zoom ring. The main gear for turning the zoom ring was slipping when I was testing it. I looked inside and found 1 of the mounting screw to be a little loose. I tightened it and everything worked fine. Again, mine was one of the first off the line. I'm guessing others won't have this issue. Nauticam does supply a nice hex key set whichcovers all the screws on the housing. It is pretty easy to check nothing has gotten loose before or after a trip.
The inside of this housing is very complex. But it feels very solid. I think it'll stand up to even heavy use very well.
