i have a couple comments

u can use on @*: rather than $me isop $chan

rather than saying if $1 == !help !kill, or !help !operserv, u can just do

on @:text:*:#:{
  if ($1 == !help) {
    if ($2 == !kill) msg $chan kill help
    if ($2 == !operserv) msg $chan operserv help
  }
  if ($1 == !commands) msg $chan the commands
}

also, u can do

on *:text:*:#:{
  if ($me isadmin $server && #nick isadmin $server) {
    if ($1 == !kline) kline whatever
    if ($1 == !kill) kill whatever
  }
}

its not critical, i imagine it works the way you have it now, but i havent tested it
