1. The official administering the throw-in (the Trail) should drop into the backcourt and bounce the ball to the thrower. This depth will provide a better view of the stack formation from the side instead of from the front, which would block the view of many of the players. I would think that an official would have a good look at a player making a curl run around the end of the stack from this position. In my opinion the actions of the players in the stack are more important to keep an eye on than those of the thrower and the probably one defender guarding the inbound pass. Those two players likely aren't going to have physical contact.

2. The Lead official obviously does not belong on the endline in such a situation and should adjust his positioning based upon the location of the players. Probably coming up to the FT line extended or even the top of the key (and possibly a couple of steps out onto the court) would put this official in a decent position to observe the action and also project a greater officiating presence to the players. Having an official standing nearby usually cuts down on the nonsense as the players have a greater sense that they are being watched.
