Seems complete enough to me, at least as a starting point. If anything tragic pops up, like you say this can be amended.
I would note one fairly obvious rule that should still probably be written: Keep ooc off the RP channel, and vice versa. ;) Lengthy ooc discussions, even about RP, should stay in the OOC channel so as not to disrupt or derail RP.
Also, in addition to ignoring someone, if you feel you must continue an argument, take it to tells. In tells, two people can be as argumentative as they like without disrupting the play of other people. Continuing to carry on a two-person argument in public is an attempt to draw others into your drama, and should be a strict no-no. Keep your personal arguments personal, not public.
And hey, I always want to nominate myself! I'm a veteran player, I'm old enough not to have a short fuse, I'm funny, and I work with puppies all day so I'm rarely stressed. I'm off every Sunday and lately have most weeknights free, even some afternoons. Back in the days of yore, I was a guide manager on AOL so I know how to moderate online, I'm tolerant enough not to kick for every small infraction, and diplomatic enough to redirect arguments into something more productive.
But mostly I have access to puppies. That's the important thing.
