Here, the 1 and 2 ball are both one balls width out from the cushion. The right edge of the two ball is lined up with the point of the side pocket.
I like to align the centers of the 2-3 to the short rail, just outside the corner pocket. There's a bit of leeway on this though. The 3-4 centers will be aligned to the short rail point of the corner pocket.
I place the cue ball along the long centerline of the table, about a half diamond away from the side pocket. Just hit straight in to the 3 ball.
