There are some that integrate into the main campaign and a few that are standalone, though I'm not really sure if they're worth mentioning(only tried a couple)…

Quests and Legends
Dark Times Act I
Alley of Murders
Tombs of the Undead

The following authors have multiple submissions:
dragonagefun, Smundell, Mengtzu

Some upcoming mods that are still in development, and seem promising given their authors have been working on them for some time:

Thirst by Sea from RPGCodex.
The Rose of Eternity
Shattered War
BG2 Redux

There are others on BSN and DANexus, so check em out if you want… Again, it has been some time since I played DAO, but the two mods I tried out were Dark Times and Quests & Legends. Unfortunately I just can't remember enough to comment one way or the other on whether they were enjoyable.

Not that I'm aware of. I take that back, there is at least one mod that affects crafting(I never tried it out myself):

The winter forge
