Another post to show my ignorance

What are all the rules associated with a player going out of bounds and back in.

Ex:

1) A1 is out of bounds, A2 passes to A1 - what does A1 need to do to be able to catch the ball legally?

2) A1 dribbling up the sideline, B1, sets for a charge but leaves a little room, A1 dribbles ball beside B1 inbounds, runs out of bounds never touching the ball, what does dribbler have to do to reestablish and continue his dribble, if possible?

3) any other strange plays?
