That's about it. There is actually another quest called 'The Lost Pilot' but that's at the north pass but it's out of the way and the xp reward is minimal.
Overall this zone isn't very efficient. It's rare to do 2 quests at once, and usually they aren't along the way. However, there is minimal grinding until the final steps when you pretty much have to grind to leave the zone at level 10. The next zone has a lot of level 10 and 11 monsters immediately and you don't wanna go in unprepared. The real problem is you'll have to grind to get there, since Don Morogh's quests will only get you to 9 ½ before you finish.
Since this is an Leveling guide, I would entertain the idea of leaving the zone and moving to the human lands to accelerate your pace. If you're going to go this route, do so while you are in Ironforge before you hit the West side of Don Morogh. However, if you're a paladin you can get a nice reward for doing Protecting the Frontier at the Amberstill Ranch, this may be worth hesitating your Elewyn Forest trip for a few minutes.
