Replying to Need help on using North American xbox 360's in Europe, KARMA WILL BE GIVEN

Ok so this summer I have to go to russia (the european part of it, St. Petersburg, if that matters) for 4 weeks, and off course my 360 will be necessary there. Now I have some questions that I think you guys could help me out with. Thanks in advance for any help.

Will I need to buy another powerbrick to use it, or can I just buy the outlet cable that goes into the powerbrick, or what? I think power is the main issue.

Will anything that my xbox can currently play work in europe? I know that they use different game/movie formats, but since it's off my xbox, it'll work, right?

I won't need a new TV to xbox cable because there the same, right?

And is there anything else I'm overlooking?
