Shari,
You should do at least a 10% water change weekly, more if warranted by nitrate levels.
You can leave the filter running, as the intake for your filter should be low in the tank, and you will not be changing enough water to come anywhere near the intake. You can leave the heater on–the limited amount of time the water level will be blow the thermostat will be minimal and not affect the heater.
The water itself that is added to the tank should be at least room temperature, if not close to the actual temperature of the tank water. You should add your water conditioner (and there are different opinions about this) just prior to adding the fresh tap water in an amount equal to the amount of water you are adding. Oh, I see you have a well, probably no water conditioner needed.
The mounting position of the spray bar depends on what you wish to accomplish with it. The further away from the water surface, the more agitation is produced at the surface and a greater gaseous exchange occurs. If the bar is at the water level, or below, you get more water movement, and, it is much more quiet.
Keep an eye on the flow of the filter return. When it starts to be reduced, you know it is time to clean the filter. Until then, just let the filter be.
