1. You cannot get all of the air out of the box, but almost all.  It is not
possible to achieve a "perfect" vacuum (even in space).  You could connect a
pump of some sort to a valve on the box, and simply remove as much air as
you can.  That is the best you can do.
2. If a rocket was going through space, and the engines were turned off, the
rocket would keep going through space as long as no other forces act on it
(i.e. gravitational pull of objects, asteroids, etc.).
