1. It seems you've already found the answer.
2. You pretty much move your camera around (animate it), set keyframes and all that, and then render. I don't know how to do that in sketchup but in Max you just move the camera, set key, move it to the next position, set key...
3. I don't have the slightlest idea how to do that... I am clueless.
