I'll add in a few myself:
For healers, stay on target. It's extremely important that if you're assigned a particular target to heal, that you keep on top of it. It can be tempting to cross-heal (and sometimes it may be necessary) but if everyone stays on top of their healing assignments, everyone should (for the most part) pull through.
For those who can lead, feel free to volunteer to lead the raid. Mark your targets and set your assignments (even if it seems like a straight forward encounter.) You'll be helping people learn how to take on the more difficult encounters in the end.
For those following, don't argue with the raid leader if you can help it. If you're following, sometimes it's best just to follow and see how things go. If you need to question the Raid leader, try to do it discretely. No one likes to be embarrassed or called out.
