Jhackrosh, I don't know if you'll check back at this thread now that it's more than a week after you posted, but I use one of the add-ons you're describing. It's Smartres2, and it comes with some silly targetname rez messages already built in, and will let you make a mass rez message, and let you add your own custom messages to the list.
One thing I had to do, though, was turn off a feature that sent people tells if they were rezzing someone that was already getting a rez cast at them by someone else. It tended to annoy pretty much everyone, but the flipside of that function is, they can stop wasting their time on that cast and rez a different target.
Also, you can get some bars that will pop up, if you want, that show you who's rezzing who, with progress-showing timers on the casts, so you can see who isn't already getting a rez right off. Since the mass spamming of rez casts is generally out of combat, the bars don't pop up and obscure the screen during a fight.
Smartres2 isn't a wholly neccesary add-on, but it's good for a giggle, and has functionality that saves you a bit of annoyance during rez-races.
