Hi Andy. Definitely match the darks to the binning of the subs. As far as flats are concerned you have to be aware of the fact that flats correct three things--vignetting, dust bunnies and pixel to pixel variation in QE (usually <1%). Flats that don't match the binning of the lights will correct vignetting and dust bunnies but not QE variation.
