A few things to note...

Flight path from Skettis to Ogrila requires Honored with the Skyguard faction.

Ogrila quests require a bunch of pre-req quests to be done before they open up - http://www.wowwiki.com/Ogri%27la

Banish The Demons quest requires Honored with Ogrila.

Need to be Revered with Ogrila to purchase cloak.

Sunfury attack plans is a random drop from the blood elves in Netherstorm - might be the 1st one, might be the 30th one.

The IQD quest Distraction At the Dead Scar is a pain - its a bombing run quest, but the mount moves very quickly, and you need to land the killing blow with the charge to get credit. Will most likely require several attempts to complete, since you'll be competing with many others to get the killing blows.

Hope this helps...

Cheers,
