Like the title says.

I've already completed the main quest, the dark brotherhood questline, and I'm about to finish the last of the daedric quests (working on HM's right now.)

I am about halfway through the mage guild's questline and I was about 1/3 the way through the TG questline until a major glitch effectively stopped me from being able to complete it.

I'm thinking that after I finish HM's quest I'l head straight over to the Shivering Isles, but before I do that I wanted to see if there were any random city quests I should check out first.

This is also my first playthough of Oblivion.

A Brush With Death (go to Cheydinall, talk with Tivela)
Shadow Over Hackdirt (Hackdirt, duh)
Where Spirits Have Lease (Anvil)
An Unexpected Voyage (IC)
The Forlorn Watchman (Bravil.. I think)
Zero Visibility (Inn north of IC)

Oh, where to start?

There's a certain Argonian that goes missing in Chorrol, which leads you to a very interesting settlement.
There's a gang of female bandits preying on men in Anvil.
If you happen to stumble across an Ayleid Statue, there's a collector in the Imperial City very interested in it.

And that's just the tip of the Atmoran iceberg.

I've completed the first three. I've read about the Forlorn Watchmen which I plan on checking out.

Any, uh ... good loot I can expect out of the last three quests?
