Yes water pump and yes common at that age. If you pull the pump, I guarantee you will see the impeller blades are worn down to flat pieces of metal. So at low RPM, what little water it can move is fine. At speed, forget it. It's just spinning metal in water.
The hose collapsing is a sign that the system is not properly venting. Radiator cap is, the hose leading to tank is clogged, or the tank itself is clogged.
