Make sure to jigger with your look sensitivity. Took me quite a while to get used to the controller after playing Oblivion on the PC with a mouse. I still think having the keyboard for controls is better in someways: I can do more things at once with a keyboard, and I can have more than just two items hotkeyed.
Done that, a little less sensitivity helped a bit. What I
really appreciate over mouse+keyboard are the smooth movements, with the keyboard is either walk or run. But yes, I still think mouse+keyboard are way better, you surely can't do http://www.youtube.com/watch?v=SB76kyYxDoQ with a controller no matter how you're good at it.
Oh hey, I just killed my first bear with a lot [I mean A LOT] of arrows
