Summarized: On the D7000 you can change aperture and shutter in LV and moviemode, and have it reflected in the preview, you just have to press (and hold down) the +- button and then turn the front or rear wheel.
I don't have a D7000, so I'm wondering if anyone here can affirm that this works.

Well, that changes EV value, which is reflected in the LV display. But it does not change aperture nor shutter speed.
EDIT: I'm saying this based on picking up my D7000, placing it into Live View, starting to record a movie, and then changing the controls as you suggested, and observing that aperture and shutter speed don't change, but EV does, and is reflected in the display.
I then changed the mode dial, cycling through "A", "P", "S", and "M" and got the same results with each setting.
As far as lending some appeal to authority to my observations: Thom Hogan's book clearly states, in the video section, that you have to set aperture prior to entering Live View mode. He also suggests that for controlling the aperture, you want to mount a lens with an aperture ring, and use that manually set aperture, which will be reflected on the display.

There is commentary in Thom Hogan's D7000 book on this. I believe you must set Aperture before turning on Live View. Then take the still or video. The limitation in Live View is that the changes to exposure settings must be made before starting Live View.
Perhaps somebody else here can elaborate. My use if Live View is only for still focus and a preview of Depth of Field, not for Movies or anything to do with exposure.

Job Well Done,
I don't shoot a lot of video on my D7000. On my D5100, that is basically the way that I would work anyway. My problem was that I couldn't see the monitor very well (reflections, etc.) so I basically set up the shoot as if it was going to be a still in Aperture Mode, before switching to Live View & Video. Videos on the D5100 have to be in Aperture Mode and Live View.
