Sometimes fords can be tricky. Try to be sure that all of the air is purged from the system. I usually do this with a manual release cap. run the engine then slowly release the pressure. then the system will stabilize. If that doesn't help then you may have something restricting flow inside the water jackets through the engine. some shops have those nifty little cameras that they can run through the system to look for potential problems. hope it works out for you. I know how how much of a pain some of these problems can be. Good luck.

you can have it done in 20 minutes with a pliers or phillips screwdriver (depending if the hose clamp has been changed before.)

The hose needs to be changed. It is most likely bulging do to the inner fibers breaking. It could have started do to over heating but can be because of age. Never the less change the hose and you should think about changing the heater core out because it may get cold and heat is nice to have when it gets cold.

yes. the impellor on these engines have a tendency to come off the water pump.First you can see if the pump is working by removing a heater hose then have someone to start the engine. if the water sprays a good, solid stream out then the water pump is good. if the water just barely comes out or not at all then the pump is weak or "bad".
