I am definitely an advocate of the fast instance or raid -- when I played a tank, I pulled pulled pulled (according to the healer's mana, of course), and even now, mostly as a Hunter, I still get impatient. When the healer's mana is full and the tank is not /afk, I sometimes just throw a Misdirect up and go. That's probably why I really liked Naissa's tips for speedy raiding -- she lays out a few really practical things you can do to get your raid moving faster, from only marking skull and X when necessary to only worrying about the healer's mana. It's not the end of the world if the Mage or Hunter has to drink for a second after the pull. While you should always get back to full before a boss pull (and as she says, that's a perfect time to break down the basics, only the basics, of the fight), usually as long as you've got the tank and healer ready, a quick pull will give you time for aggro to settle down as well.
I don't completely agree with her DPS meter remarks -- I do think that beating the raid is much more important than trying to win the DPS meters, but as a DPS player, I like viewing the meters as good feedback on where I should be. If I'm super low in the meters, it's time to look at my gear and rotations and try to figure out why so I can get better, and I think it's valuable for DPS, as long as they can keep their attention on the raid, to do the same thing.
But all of the other tips are great, and in general, "pull pull pull" should be the order of the day. Some groups are better at rolling through content than others, obviously, but as long as you've got a solid tank and healer in play who know the instance and know how to handle what comes, most raids and groups can move through the content pretty quickly.
