Sweeping with few taps thrown in at the top of a phrase is perhaps the most complex and interesting guitar technique on the map. With your wrist resting lightly on the lower strings to mute them when not being played. Less movement up and down means more efficiency and less noise.
A suggestion I’d make is to make sure to alternate between the three fingers on your tapping hand to help strengthen them. The pinkie is smaller so it is especially useful on the higher frets. Be sure to experiment and see what works best for you.
