She would need a UK work visa.

You can but be aware, that the UK citizen cannot legally change their status while in the US. It depends on where you both want to live. If the US citizen wants to come back to the UK, a marriage visa is needed from the British Embassy in the US. However if the UK citizen wants to live in the US, they will have to go back to the UK and the US citizen will then need to file the I-130. Until it comes through you cannot live in the US, but will have to wait in the UK.
US prepaid cards cannot be redeemed on an XBOX Live account tied to the UK.
I would rather support my country and go with that choice. I don't understand why anyone would want to go against their own country. Both places need jobs.
The UK
The answer to this question depends on where you live, although you would never normally say " I live at Tara Street" at all. If you live in the UK you would say "I live in Tara Street" and if you live in the US you would say "I live on Tara Street".
