A couple of rules questions

[CoachTex]

I was the scorer for several games this weekend for a tournament. Out of 17 games, there was only 1 "what do we do?". I ask you if the officials came up with the right answer.

Jump ball, team A has the possesion arrow. Team A takes ball out on the baseline, player starts running the baseline like a made basket. Ref blows the whistle, calls the violation. Team B takes ball out, throws it in and jump ball immediately occurs. The official making the call says team B's ball. Other ref says team A's. Both refs discuss and give ball to team A. Should have the possession arrow changed after team A's throw in violation?

Next question is just something I observed and have no idea if it's correct. Player A1 passes to A2 but ball is tipped by defense. The ball is rolling along the floor. A2 tries to get the ball bouncing while chasing it and the ball just keeps rolling. He is unable to get it to bounce after about 4 or 5 slaps at it. Ref blows the whistle and calls traveling. Correct?
