Things I should know about importing 360

I am from UK and let's say I simply can't wait a whole month while US already gets their hands on the new 360, so I have considered importing it.

I already did some research and I know that some 360 games are regional locked depending on whether the producers choose to or not.

What I couldnt find was what impact will it have if I play Xbox Live? Will my US 360 try to connect to the US servers of XBox Live? Will matchmaking trying to match me to US servers or will I be connecting to UK/Europe games/servers?

Thank in advance.
