Jump Ball - non-jumper position

[MelbRef]

I've had a few games where, prior to the jump ball, a partner asked a non-jumper to:
1) not stand behind the opponent, when the two players were at the top of the key.
2) not straddle the division line
3) do not move prior to the toss, when the player was not along the center circle

For #1, I think this only pertains to non-jumpers along the center restraining circle, specifically within 3 feet. There is a case on this, but where is this in the rule book?

For #2, phantom rule?

For #3, same thing as #1 I believe, only applies to players along center circle
