maybe i'm desensitized about this, since i moved an hour...and then 18 hours...in the span of two months last year...but i would think a heater and an air pump are unnecessary for such a short move. there's not going to be an O2 problem is the fish are only in the container for a couple hours, and unless it's particularly cold, a heater isn't truly needed. nonetheless, the cooler idea is solid. i used two medium-sized coolers...this way i was able to pour the water into the tank after i got going, thus eliminating the siphoning issue.
as for moving the water, joe makes a good point. if you could test the pH and hardness of your new house and compare it, that would be a good call. this way, if it was radically different, you could focus on bringing more water. if it was about the same, then you wouldn't have to worry about water in excess of what your fish are travelling in.
