Would you replace the water pump on a 4.0L 93 Ranger with 120,000 miles if you had the radiator out?

I have been having an overheating problem with my ranger the last couple of weeks, who knows maybe it was the water pump impeller that broke when it made some horrible noises a few weeks ago. The fan clutch was spewing silicone grease all over so I replaced it. The engine still got hot so I replaced the thermostat with the 198F stock unit. When I flushed the system and pressure tested it I heard a hiss from the radiator around the top hose area. I replaced the clamp and it still hissed so I have removed the radiator for service. Is the radiator serviceable or is a replacement only item (Aluminum with plastic end caps).

So while I am here with it all torn down should I replace the water pump?
