Agree on the first point, but not on the second. Once A2 touched the pass, A1 can recover and dribble.

The key in the play is determining whether it was a fumble or a pass. If it was a fumble, then it can be recovered, but A1 has already used his dribble and any further dribble would be a violation. If it was a pass, then it becomes a dribble (and a violation) when A1 is the first to touch it after it hits the floor. (And if it was a pass, but A1 caught it before it hits the floor, it's a violation if the pivot foot moved.)
