Wash, then Detail
When you wash your car, what do you do? You wash the majority of dirt off, then you dry it, then you detail it, right? Think the same thing for your teeth/mouth: brush everything, then go back in and get in all the nooks-and-cranies by flossing
When you're done flossing rinse everything our with scope, listerine, or whatever else you may like to use. Either way, do them both everyday!
