For the other questions, the NerveGear reads and intercepts the nervous signals produced by the brain for the player to be able to move their avatar without moving their real body (so that they wouldn't run into a wall for example). Then it induces signals in the brain based on what the avatar is doing, giving the brain the impression that it is controlling and feeling what the avatar is doing.
