This is a rough draft, and an idea I had as a new tank breaking into Outlands instances. It is meant to be a desk reference for new tanks, so they can be proactive in knowing how to handle an instance, but specifically trash packs, which don't seem to be covered in much detail in other guides I've read.
The info stated here comes from personal experience, as well as some info from WoWWiki, especially as some details I forgot even just after running the instance for the first time.
Please post feedback, just remember the guide is meant to be a quick reference instead of a book, as much as can be helped. Also, there are probably errors in this document! Please let me know where they are, as I'm a new tank too, and don't know the intricacies of every class and every possible group makeup.
If there's a good amount of support, I plan on creating one of these for each 5 man. I've already got part of Shadow Labs written.
I know some people will say 'oh this is old news' or 'this is data duplication', so the idea here is it's for new tanks and also mainly for marking and handling trash, which I feel is not sufficiently covered in other guides to create a proactive approach to learning instances instead of a reactive, gold-costly approach to learning, e.g. wiping.
