A) There are structural advantages to keeping as much weight as possible in the outer wing. Therefore, the center tank is not fueled unless needed for the range, and if it is fueled, it is used first. B) The B747 can be ground conditioned, but if ground AC is not available the APU is used to drive the aircraft airconditioning system, which does create a lot of heat in the area fwd and under the wing.
