I looked at #3, and I think Björn makes a good point that the main thing you need at this point is more experience with the medium, as there are a number of things that aren't quite accurate, such as confusing tilt with swing at certain points, and, for instance, even though you can correct the shape of objects with rear tilt, when photographing a tall building it would be much more common to use front rise, because rear tilt alone will introduce a focus problem, and using front tilt to solve the focus problem will require pointing the camera up, and before you know it, you've applied indirect front rise, which is effectively the same as using front rise to begin with.
So here's what you might try--for everything you want to illustrate, make a photo, scan the photo, and cut a slide of the image into the video. For instance, if you want to show how to photograph a tall building with a view camera, take one straight on shot of the building, one pointing the camera up on the tripod, one attempting to correct perspective with rear tilt, and another with front rise and the camera level, and explain each photograph, also showing the movements applied to the camera. You could shoot the video in the field and cut the slides in later. I think this kind of approach might both firm up your own knowledge and help you make a more useful video for others.
