Bring in is the lowest card, subsequent streets is the best hand. What constitutes the best and worst hand depends on the variant that is being played. There is no position in stud unless it's Mexican Poker or some other obscure variant with a button.
Technically that would be a call because the $1 isn't in play, but I would probably just announce it as a raise and see how the players react. Any resistance by any player in the hand and I'm calling the floor and making them decide.
The only guidance I've seen on fanning the stub is from the WSOP dealer guide. TDA doesn't get into things like that. Different dealer schools probably teach slightly different techniques.

One player at a time can buy the button. S3 gets first choice. If they wait, choice goes to S4, etc. Some rooms will also allow the next person to come in with a straddle, but they still have their missed blind/new player status and would have to buy it the following hand. Everyone else has to wait their turn. I've had extreme cases where 6+ players left and 6 new players sat down all at once. I just said screw it, I'm treating this as a new game and drawing for the button.
