Throw in issues HS Rules

[HokiePaul]

1) I grant the time out. I would consider the ball still at A's disposal.
(8-3-a: The ball is at the disposal or in control of a player of his/her team)

2) Violation. Spot throw in from the endline for B.

3a) I'm going with no violation (may change my mind once I hear what others have). I'm treating the wall like the floor out of bounds and considering this like a dribble - and there is no restriction on dribbling during a throw in.

3b) I'm calling a Violation (and I'm looking through the rule book now to see if I can figure out why).
