As far as "shaking hands" goes, you'll just want to use higher shutter speeds (1/250+), and higher ISO to achieve it as needed. I've known photographers who were in the early stages of nervous system disorders, and this was their fix. It also helps to learn how to breath (and not breath) when shooting. Same for learning to press the shutter button, without pressing/moving the whole camera.
