Why not use all drilled holes for drains so you can setup a dual herbie, then just run your return behind and over your tank.
And the dart isn't a bad size for the tank, a little big but nothing it couldn't handle. Personally I would go with a good quality internal pump for noise and reliability but that's just my personal preference.
