Soubar does have two quests from Lozeng and a halfling (forgot the name).
Don't take the quest from the innkeeper it is bugged.

Underdark Quests.. It's a bit dated but the only change is a new quest in the Mistlake Outpost from one of the svirfs there taht wants to get some materials in an adjacent area full of earth elementals, CR 20).

And there is a thread about the quests in the Upperdark.

Durlag's Tower does have several quests too, some are only for high epic lvls or in group (I heard this is doable by surfacers and UD chars).
