Gary,
your approach is good. I would have the settling tank at one end and filter + pump at the other end too. And use big pvc pipe to connect between the settling tank to the pump intake valve. for example, if you pump intake valve is 2", use 3" pvc pipe. why ? bigger pipe to provide lots of water available at pump intake valve. no worry about water starvation at the pump intake valve. Pump use its energy to push out the water so placing the pump close to the filter is more desired.
