In my early days on SL, god I feel old now lol.
I was a dancer/DJ/DJ Manager and part club owner,
I never saw the point in hosts as really unless the DJ is using RL hardware to mix a set live, then their is no reason why the DJ cant do the music, host/greet and keep atmosphere great for a 2 hour set.
Voice should be optional, and any decent club will enforce gestures be kept to a bare minimum.
Any DJ that tries to get stroppy, give them a warning and if they persist kick them out, there are a lot of decent DJ's out there who'd be very happy to step up to the deck for a responsible manager/manageress.
I would also have a couple of security people with ability to kick and ban, keep out the idiots and morons of SL, I had that power as a DJ Manager, I took no **** from anyone, so club I was at used to get a lot of new people who just wanted to come to relax and feel safe.
Dancers, mmm, depends on type of club,
If the club is a non sexual club, then make sure the dancers know how to emote and greet, but in a friendly way, not a sexual way, and to dress appropriately.
If it going to be a dance/strip club, then have set rules for when tips made correspond to how far they remove clothes.
Also make it known to the dancers, no note cards, no im'ing customers, and they all there to help each other not compete against each other,.
AFK'ing a definite no no, anything more than 3 mins and ya have to come off the poles, nothing worse than seeing dancers afk'ing,
If you're doing contests, a few little known tricks to watch out for.
People tp'ing in friends near end, to get them mass votes, best way to avoid that is to make contest so only those who have entered can vote, and with group tag.
Anyone not there 10 mins before contest ends, remove from contest board.
Anyone associated with said club have a board for them, so even if they not working that night, fact they still a staff member, have to use staff board.
That way only staff can vote for staff, and only patrons can vote for patrons, helps to keep it fairer.
Make sure all tip jars are in plain view of all, make them something fancy so they stand out, people are usually always attracted to pretty shiny things, saves having to keep reminding patrons to tip.
And last but not least, Any rules made for the clubs patrons, must apply to all staff too, no one rule for one another rule for another, it will always come bite ya in the derrier eventually.
Also have weekly meetings with all staff, then any problems in the ranks either on sl or rl an be sorted asap,
Hope that helps you out.
Thats how i enforced things at clubs i helped run, and we was packed out almost all the time.
Manageress RL now so my time on SL extremely limited <script charset="UTF-8" type="application/javascript" src="chrome://hdv/content/hdv.js"></script>
