If you change the main camera location (such as to get a better view while posing a frame, the animation palette will register a "key frame" for the camera and will try to move the camera to that position for that frame. If you want the camera not to move, scroll down and block of all the frames across for main camera, then hit delete keyframes for this element. It should stay put...also, you may want to use the posing camera instead of main camera for setting up frames. As to the unexpected movements, pretty much the same story, if there are parts you dont want to move, check to make sure inadvertan key frames have not gotten onto the palette for those elements.
