Not at all certain where you were going when you left mid-sentence, but here's my take. Once a player has established his/her pivot foot, he/she may only lift that pivot foot to pass or shoot. It's legal as long as a pass or shot is executed before that pivot foot touches the floor. The action of the other foot is not a factor, so yeah, a long step and a shot is legal. It seems inconsistent, but if it were not legal, there would be no way to execute, for instance, a hook shot. Or even a layup. The player is allowed one step after the pivot foot is established, as long as a pass or shot is taken. If the dribble is still available, it must be STARTED before the pivot foot moves.
