This may be helpful to someone of any class, not hunters.
I've been doing the rep grind a lot this week with Spiderheart as I wait for Akaa to close the last few levels so that we can hit Northrend together, and because Akaa (as noted in a previous post) is way ahead of Spider there and gosh darn it I want funky mounts too. Now, I'd known in a vague sort of way that Wowhead will let you look at data collections, but never checked its rep listings.
Take the one for Exodar reputation, which I've been on most lately. It shows all the quests that give Exodar reputation, which I wanted. But it also shows all the quests that give overall Alliance reputation, since that's added to all the groups within the overall category. With these reminders in hand, I could and did spend a few hours in Alterac Valley battlegrounds and save myself 30-odd stacks of runecloth turned in to the cloth quartermaster in the Exodar.
Gotta like that. I'll certainly be making more use of this in the future.
