Wetting the outside could cause problems with the glue holding the veneer on the outside but you are not trying to soak it just wipe it with a wet cloth and let it dry on it's own. The idea isn't to swell anything up so much as to equalize the ratio of moisture between the inside and the outside of the board. I would ignore the cabinet joints for now, get the sides flat first.
