Need help translating some parts of the theme

Hi, I am using your en_EN.po file found in the languages folder to translate the site into swedish. But there are some parts I just can't seem to be able to translate.

The first is "currently powering X blogs" which can be seen top right of the site. I've been able to translate currently powering but not the "blogs" part.

The second is the date in posts and also in widgets (only recent posts widget tried so far). For dates it uses for example 16th, 17th and so on which is correct in english but for a swedish site that doesn't look the best. Any way to fix so it only types the number?

Thanks
