Yes. I have also left the pan and just filled the timing cover groove with blue goo. And I've taken screwdrivers and gotten the seal in too. But my point is that this is a job that CAN have scope creep-you just have to decide how deep you want to go (and how "right" you want to do it).
I would not automatically change a water pump with a radiator change. If the pump is not leaking, the bearing feels OK, and it has been wet I would leave it. On my '83 K20 I changed the pump once and it promptly broke the shaft and threw the fan at my pretty new radiator. Luckily it was at idle and the belts retained it from doing much damage, it just chewed up the shroud a little and I replaced a belt. So I don't change them "just because" anymore.
