[The Matrix] Once someone's body has been co-opted by an Agent for their program are they forever gone and replaced until they die? If so does an Agent have to kill their current host first in order to transfer themselves into another body in a different location?

Nope. 

When an Agent possesses a bluepill's body, the bluepill basically goes unconscious. When the Agent abandons the body, the bluepill will wake up, very likely confused at their sudden loss of consciousness and/or ending up in a different location or suffering serious injuries. If the Agent is killed whilst possessing a bluepill's body, the bluepill will be killed as well.

That poor homeless dude who Smith possesses to fight Neo? Dead. The pilot the Agent possesses on the rooftop? Dead. The two truck drivers the upgraded Agents possess in Reloaded? Dead. The cop who gets possessed by an upgraded Agent during the highway scene? Alive, probably suffering some bruises, and likely very fucking confused as to how he went from being in his cop car to being in the middle of the highway. Probably...uh, had an accident or something.
