Travelling & lane violation

[Rock]

2 questions...thanks..

Two players from the same team both come down with a rebound, player B releases the ball without moving, player A jumps without stepping and shoots the ball, is this a travel because two players from the same team had possesion of the ball?

A player lines up in the last block of the freethrow lane prior to the referee giving the shooter the ball. Under the new UIL? rule the player is not allowed to occupy that last block. When the ball is shot and missed the referee whistle's a lane violation for the player lining up in the wrong block. Is this the referee's responsibility to align the players prior to the free throw, or just a courtesy type of deal, and is it really a violation to occupy the wrong block on a freethrow?

Thank you
