I teach banjo. One important consideration is whether to place you right hand ring (3rd) and pinky (4th) on the drum head near the bridge. Although it is traditional I don't recommend it.

I usally teach Bile Them Cabbage or part of Cripple Creek first.

I recommend doing the rolls using sympathetic movement. It's a fairly complex concept but basically your fingers move in the same direction.

Most banjo teachers don't understand "Sympathetic movement" of technical muscular concepts such as uniform joint movement (a right-hand problem with some pickers).
