I'm leveling my priest team right now (my moonkins are 80) and they just hit 71. I've done most of Borean Tundra and am about 1/2 way through Howling Fjord. I never did it before, so this time I started reading the quests instead of going directly for the objective. It's actually really helped the boredom - there are some cool stories and questlines that make it a little more entertaining.

For the most part the default UI has a pretty good questhelper and you shouldn't be needing to search on the internet. I do, however, check how many quests are after a collection quest to see if it's worth my time. Often if it's chained with another collection quest then I just skip it entirely. I think there are more than enough quests in WotLK that you could skip the majority of collection quests and do just fine.

When's the next AV weekend?

Also, it sounds like you just hate the game right now may be time for a break
