Player location is determined by where they are touching the floor or where they last touched the floor if they are airborne.
1st. question: player who dived out of bounds must be touching in-bounds and nowhere else before retrieving the ball.
2nd. question: may be or not a violation.

This post RESUMES the topic

About the NBA Rule:
•  The ball is out-of-bounds when it touches a player who is out-of-bounds or any other person, the floor, or any other object on, above or outside of a boundary or the supports or back of the backboard.
•  Any ball that rebounds or passes directly behind the backboard, in either direction, from any point is considered out of bounds.

About the FIBA Rule Nr. 5:
Art. 23 Player out-of-bounds and ball out-of-bounds.
23.1 Definition
23.1.1 A player is out of bounds when any part of his body is in contact with the floor or any object other than a players, on, above or outside the boundary line.
23.1.2 The ball is out-of=bounds when it touches:
•  A player or any other person who is out-of-bounds.
•  The floor or any object on, above or outside the boundary line.
•  The backboard supports, the back of the backboards or any object above the playing court.
23.2 Rule
23.2.1 The ball is caused to go out-of-bounds by the last player to touch or be touched by the ball before it goes out-of-bounds, even if the ball then goes out-of-bounds by touching something other than a player.
23.3.2 If the ball is out-of-bounds because of touching or being touched by a player who is on or outside the boundary line, this player causes the ball to go out-of-bounds.
23.2.3 If a player(s) move(s) to out-of-bounds or to his backcourt during a held ball, a jump ball situation occurs.

Commentary: From the said above, we understand that the rules for both NBA and FIBA are quite the same: the ball can touch edges of the backboard, however when the ball touches back of the backboard (or the supports) it is out-of-bounds.
It is important, before closing this commentary, to read the related topic about Rule 4.35.2 at "Out of bounds: with BOTH feet ?" as part of this summary.
Once in a game under NBA based rules, a player recovered a loose ball at high speed near de side line, proceeded to dribble but was losing his balance trying to stay in bounds. The player in this case put the dribble down, touched out-of-bounds briefly, and then touched the ball again only after returning to the playing court. There was no call  from the refs. In U.S.-based rules, one can make an argument for that being called out-of-bounds, but one can also make the case that it was an "interrupted dribble" and thus did not meet the criteria.
