3 Man System. How to Re-Load?

[JEL]

Don't get a chance to work 3-man as much as I would like, but work on it as much as possible anyway.

After a "rotation" where the PU ends up at 3B, what is the accepted procedure to re-set positions when play has ceased? Does PU stay facing infield (and ball) until BU's get into position, or vice-versa. Come to think about it, How should it be done in the 2-man?

Also, if PU keeps watch after the play, should s/he remain stationary, or is slowly backing up out of the infield while still watching acceptable?

Just really trying to gear up for August! want to look as sharp as possible!
