If you are not changing character sets for Chinese or Japanese you will find Spanish, French and German to be your best choices.
Use the proper meta tag for each page's language, however you'll find that Google and AdSense don't need that and will detect the language of each page automatically.

2) Do I add the translated pages to my existing domains or put them on new domains?
I have no idea if or how this affects AdSense because I've never put AdSense on a site with another language, but in a general sense, when I've done sites with translations, I've put those pages in directories called /de or /cn or /en. Google does a fairly good job of figuring it out.
