i'm exalted on 3 and 8k from exalted on 4th (5th is inscriptor), the thing I do is park one guy in the valley when I am raiding naxx on my mage or pally and during down times (and there are always some) i fly around grabbing everfrost shards. Make 3-5k/day rep easy this way, just need something like mapster and very sharp eyes.
