Questions

I was observing a game last night preceeding the game I officiated. A couple of situations came up which got me thinking about how I would have called the situations.

Question 1: I know this should be easy but I can't seem to find the correct rule. When a player is at the free throw line at what point has the thrower violated for stepping over the line? If the thrower steps over the line while bouncing the ball in preparation to shoot is it a violation or are they allowed to place their foot behind the line and still attempt the throw?

Question 2: Team A has a throw in from their frontcourt. A1 inbounds to A2. A2 has control in the front court. He mistakenly thinks the basket in his backcourt is his goal. A2 dribbles in for an uncontested layup in the opponents basket. Team A takes the ball out and play continues. The officials did not make a call (perhaps their judgement was A2 didn't have control in the frontcourt-who knows). If the officials recognized that an error was made in not calling the backcourt violation could they cancel the score as listed in the correctable errors section or is this not a correctable error?
