How far (distance) from the sun will a comet sublime to the vapor state (Approach) or condense to the solid state (Depart)? If the water gas was to collide with a planet would it put an ocean on that planet and change the orbit?

It depends on the abundances of gases and water there is in the particular comet. Hale-Bopp is still sublimating some 11 years after perihelion.

Good question.
