I would put a "foot valve" at the end of the pipe that goes into the well. It keeps the water from back flowing. Then open the fill valve at the pump and fill the whole pipe going into the well. When the water stops going in, close the valve at the pump and start her up.
What's nice about this setup is that when you shut the pump down for an hour or a week, you don't have to reprime it every time.

Whatever size pipe you have in the well restricts how many GPM the pump can move, no matter how big the outflow pipe is. However, smaller might be better in this case, because how far you are trying to pull the water. The pump is not going to work as good as it is rated because of the pulling distance. Then if that water level drops in your casing, it is going to have to pull further, creating even more work on the pump. Hopefully the water level never drops.

Pumps can push water more easily than pull water. That is why a submersible pump works better.
