Zchinque: By now I really think you're not giving new players enough credit. It's somewhat patronizing to suggest they would need what is essentially a non-player to guide them through everything and hold their hand. Somehow the rest of us managed to become more or less functioning mafia players without it.
Besides, I doubt we're going to completely fill a newbie game with only new players anytime soon, so there's bound to be a couple who has already been in a game or two.
For me, I find it less guiding, and more, answering questions that we can afford to answer. No lynching on day 1 is something that sometimes pops up and having a player rationally explain why this is bad prevents people from going into a game where the experienced players jump them for suggesting it.
I suggested a stump because I don't want an experienced player to become a crutch that the newbies use, the option to kill them off prevents them from getting too involved (granted, you can post restrict them).
