Though I am not a Henchman (I have no LGS so my application would be denied) I am the community leader for my group. If you are looking to expand and provide a good experience for the players that look to you here are some thoughts:
1) Remember you are the host, not the boss. Encourage play but don't dictate how it is played.
2) If it is either you or another player who has to sit out, then you should sit out, the community takes priority.
3) Have a demo crew together, something simple, painted and balanced against another demo crew, a great looking demo table helps.
4) Have a 'loaner' crew. Something (again) simple but strong enough to stand on it's own but also something you aren't invested in so that you are always willing to let someone play with it.
5) Observe your group and be willing to provide feedback and rule calls but don't butt in or correct rules unless you are asked.
6) Finally, always try to push towards a positive and encouraging environment that is welcoming to everyone regardless of the player type.
