The function "resethealth" requires a reference to be attached to it. The syntax is ref.resethealth. However, this function does not revive, it simply resets their health/limbs if they are alive. Cells respawn every 3 days i believe. You can modify this, look it up at the geck main page.

To modify a GameSetting you will need the fallout new vegas script extender.
