Why does Spanish double the letters in EE. UU.?

Spanish abbreviation rules double the letters when a word is plural. Since Estados Unidos contains two plural words, the abbreviation becomes EE. UU. (with periods and a space). This convention also applies to other plural abbreviations.

Is it wrong to say americano for someone from the United States?

It is not grammatically wrong, but it can be considered imprecise or culturally insensitive. In Spanish, América refers to the entire Western Hemisphere, so many Latin Americans consider themselves equally americanos. Estadounidense is the unambiguous choice.

Do I need the article los before Estados Unidos?

It is optional. Traditionally, los Estados Unidos was standard, but modern journalism and speech often drop the article. Both los Estados Unidos and Estados Unidos are correct.
