Dustwallow Marsh 38 - 41
At the entrance to Dustwallow be sure to grab the 3 quests at the Burned House(1). Once you have them continue to Brackenwall Village(2).
Grab all the quests in Brackenwall, then head east to the tower for "Twilight of the Dawn Runner"(3). The Blood Elf you need to save is on the first floor and the cargo is at the top. When you're done that quest continue east to "The Hermit of Witch Hill"(4) Refresh your quest and accept the two new ones. Start killing the undead and frogs in this area until you're done both quests, then return to the hut and refresh both of them again. Run along the waters edge and collect 
9 Witchbane. Once you have all 9 return to Mordant, and accept the followup. Run to the end of the dock and plant the torch there. Kill Zelfrax who comes flying down at you and turn in your quest. Now head back to town and turn in both of your quests. Accept "Help Mudsproket" then head south out of town to Ogron(5). Accept "Questioning Reethe" and protect Ogron through the battle. Return to town to turn in your quest.
Now head south to the Shady Rest inn, turn in your quest and continue south to Mudsproket(6). Grab all the quests and the flightpath, then head south and start killing Dragonkin and collecting 
Wyrmtail(7). Once you have all 8 wyrmtail head northwest to the Raptors. Here you have to kill Goreclaw(8) and enough raptors for 
5 Bloodfen Feathers. When you're done return to town and refresh your quest supply. Now head northeast to the Stonemaul ruins, Grab 
Mok'Morokk's Snuff(9) on the eastern side of the ruins and then head to the Den of Flame to the east. Outside of the den is 
Mok'Morokk's Grog(10), once you grab that head inside and start killing the dragonkin. Use Brogg's Totem on their bodies while you kill your way through for the Strongbox and Stonemaul Banner.
Before exiting the cave make sure you've killed at least 5 Scalebanes, then outside finish off the remaining Ash tails and Scouts that you need before heading East to Tabetha(11). Upon ariving at the hut turn in your quest and grab all the new ones. When you're done head east to Beezil's Wreck killing Crocs with the totem down as you go. Once you reach the Wreck speak with Moxie(12) and refresh your quests. Search around the crashed Zeppelin for the 
Seaforium Booster Crate. Once you have that start disolving the oozes by useing the ooze buster when you're close enough to a power core fragment to see the electricity jumping from it to you.
While you're dissolving the oozes keep an eye out for 
Zeppelin Cargo scattered throughout the area. Once you're done both quests return to Moxie and turn them in. Accept the only followup then head north to the river and kill the remaining crocs that you need for "The Grimtotem Weapon".
Also if you where high enough level at the time of turning in frostmaw kill Deadmire(13), the albino crocodile in this area.
When you're finished head further north to "Direhorn Raiders"(14). Here you need to kill 12 Taurens and the undead in the hut, Apothecary Cylla. Make sure to right click the Sealed Envelope for a Start-A-Quest-Item. When you're done head west and kill Darkfang Creepers and Noxious Shredders for "The Reagent Theif"(15). The optimum place for killing them is northwest of Tabetha's Hut. When you're done head back to her hut and turn in all of your quests. Then head back to Mudsproket and turn in all of your quests. Accept "Spirits of Stonemaul Hold" and head back to the Stonemaul ruins.
Kill 10 Stonemaul spirits and the rest of the whelps you need for "Identifying the Brood". Return to Mudsprocket when you're done and turn in your quest, accept the followup then fly to Brackenwall, turn in your quests and do the talk-to-back-and-forth thingy until you have the quest to destroy 5 eggs. Then fly back to Mudsprocket and head south to Onyxias Lair(16). Plant the banner out front of her lair and kill the dragon that comes out. Then head to the valley behind her lair and destroy 5 of her eggs(17). When you're done return to Mudsprocket and turn your quest in, then fly to Brackenwall and turn your quest in there as well.
If you're a class capable of soloing a 45 elite (Hunter) Then accept "Challenge Overlord Mok'Morokk" and get him to about 30% and he'll run from town.
