For a tank this size, I'd just keep it simple so you have more room under the tank. I'd do one return line with one outlet. Use powerheads in the tank for the waves. Your return should not have enough flow through it to contribute much to the flow. Too much flow through the sump will sweep microbubbles from the skimmer into your display which will make the water look hazy and may even irritate the corals. 5x the system volume is a good number for the return pump.
