Keep in mind the following - 3DS games are region locked, either Japanese, EU + Australia, and US/CAN versions. This region is the only important factor, not your geographical location. You can use a US 3DS in the UK just fine with a UK charger, but, you will have to import US 3DS games as EU ones will not play on it. You can purchase digital games from the US eShop, but you must buy $US wallet top-up cards, these are currency and country locked so again a £UK one will not work.
No, temple run is not released on the 3DS.
No, you cannot register a Nintendo 3DS from a different region.
