Easy Armor, a bit of Money and some Potential Training.
This is for you greedy little children that don't mind (or enjoy) stealing. :]
When you arrive in the Shivering Isles for the first time(I don't know how it is exactly; I have the expansion pack for Oblivion), go to the city "Passwall".
Make sure you have the difficulty setting on the easiest possible (Hit Start, Gameplay, and put the slider to the far left. It's like magic.)
Talk to the people as you see fit, and get the information you need for the mission.
For the Armor:
Go to where the Gatekeeper is surrounded by the dead guards.
You can sneak up to them and take their armor, just make sure you can run fast enough if the Gatekeeper sees you.
There you have it!
For the Money:
Go into the inn, "The Wastrel's Purse".
If Dredhwen is the only one there, wait until she is asleep. (This happens often)
You can usually steal things without her even noticing!
However, you can kill her and take what's on her, as well, then steal whatever you like!
If that crazy mayor man comes after you, just kill him or run away, it shouldn't be hard. He's not too terribly skilled. (The one to watch out for is Nanette.)
If you need to, you can go up onto the tree near one of the houses (it has two roots extending over the water you can jump up onto), and fight with a bow from the house roofs.
Hope I helped. :]
