Got it. had to do lots of group qs though, this is where I found quests:

Argent Vanguard

Crusader's Pinnacle

The Fleshwerks (camp atop the mountains to the east)

Escort a priest in northeastern Fleshwerks (can only be done after the battle between the Argent Dawn and the Fleshwerks mobs has started)

Onslaught Harbor (camp on the mountainside to the east)

Onslaught Lockboxes in the Harbor drops quest start item

The Bone Witch (in a cave in southern Jotunheim)

The Shadow Vault

Below Icecrown Citadel (entrance on western side)

Atop a hill in front of Icecrown Citadel and little to the east is a quest giver that ends in 3 5-man quests)

Inside the Underhalls in Northern Jotunheim (by the arena) is a mob that will give you a quest

On the Skybreaker is loads of quests, many end up in dailies but be sure to do them all as there are many chains aswell

In Sindragosa's Fall you'll find that little Matthias kid that also has qs in various other places I've mentioned. He's a ghost though, so might wanna check for the exclamation mark on the map

At the feet of the mountains that surround Ymirheim, is a camp on the eastern side with a few quests.

Can't say I wrote them all here but at least it could guide you a bit, most of the places you will end up if you follow questlines, though. Cheers!
