Since i will be utilizing slower flow in the sump, about 350-500 gph, will a herbie be able to be dialed down to flow of about 350 gph AND still have its silent factor?

For sure. You could dial back a 3" herbie down to 5 gph if you wanted. As long as you're not pulling air into the drain it will be silent.
