Is this correct?

Where's the new throw-in location?

Since the kick is not a legal touch the team A throw in never ended so the ball should be inbounded on the base line in all cases with the right to run the endline since the throw in is after a made goal.

The ball continues to midcourt where A3 and B3 commit a double personal foul while going for the ball, but before either player is able to touch it. The official sounds the whistle for the double foul with two seconds left. How is the game resumed?

The Team A throw in ended with the legal touch by B1, you would resume with the appropriate restart for a double foul in in both NFHS and NCAA.
the difference being that there is team control during a throw-in in the NCAA so there would be POI to restart play. So the ball would be inbounded near mid-court spot throwin nearest the double foul for team A
I believe it is POI for NFHS too, but on a double foul since there is no team control here you go to the AP. the inbound would be spot nearest foul call.

The pass is deflected near the point of origin by A2 who is standing inbounds near the thrower, but the ball continues in flight and strikes the backboard of Team B. The official inadvertently sounds the whistle. The AP arrow favors Team B. When play resumes who get the ball and from where is the ensuing throw-in?

The Team B throw in ends when the ball is legally touched by A2 the ball striking the backboard should be irrelivant since the backboard in the back court is the same as the floor (for team B).
NCAA there is is team control during a throw in so Team B gets the ball POI on the end line spot throw in nearest where the ball hit the backboard.
NFHS there is no team control during a throw in so since the throw in ended there is still no team conrol when the inadvertant whistle was blown go to AP inbound end line spot throw in nearest where ball hit backboard.
