Jurrasic or Vets...Help with rule

[RookieDude]

I need a rule reference please.

I found a computer here and wanted a quick reference from you pros.

Situation:
Player A1 is dribbling the ball...his momentum takes him OOB without the ball...he establishes himself on the court and retrieves the ball again.

Would like a quick rule reference to show this play is legal.

Situation 2:
Players run around opponents side of the court during pre-game warm-ups...T for unsportsmanlike conduct...is this charged indirectly to a Head Coach such as a dunk in warm-ups is...thus giving him the seatbelt for the game?

Thanks in advance.
