You've probably done it but you have to let the air bleed out of the system by sliding the heater hose off and letting air and coolant ooze out until just coolant comes out. An air bubble can foul up things pretty well.
FWIW, my overflow bottle does not seem to change volume much, maybe 1/4 to 3/8" between cold and hot. And my gauge almost always stays between "o" and "r". If I'm stuck in traffic, it creeps up to the right side of "r" but that's it.
I'm glad to hear the pump helped out.
