I'm pretty sure all you have to do is set both the blog's and author's locale to the language you want. Blog #1 is an aggregator blog, so it will be in whatever language it has selected, but posts will always be in the language of the author.
b2evolution doesn't translate posts, so the 'stock' text on the page is in the blog's locale/language. Stock text for each post (like where it says "comments" or "author" or "words") will be in the author's locale/language.
