Yes, that is normal, it starts tracking as soon as it is powered.

It's normal. The Earth rotates with regard to the stars once every sidereal day (it is not quite 24 hours, but that's not important right now). So your motor is doing the same, but in the opposite direction, thus tracking the point you have your scope on (this all depends on a reasonably accurate polar alignment).

This movement is in RA (right ascension). It must be RA because if you consider the co-ordinates of an object at the zenith it's declination is always the same (for a given latitude), but the RA changes through the night.

Yes, if you have a good polar alignment then the motors will keep the star in the eyepiece field-of-view, at least long enough for you to pop indoors to make a fresh coffee :(
