Nothing in New Vegas spoils Fallout 3. They take place in 2 completely different corners of the country. And New Vegas can not spoil anything for Fallout 3, as New Vegas takes place before the events of Fallout 3. Hope this helps! Also Fallout 3 is not a sequal. But lets pray for a Fallout 4

I could imagine that it takes place in America just like every single other game in the Fallout series.
