WordPress themes for multi-authors?

I’m starting a multi-author blog but so far I’ve found nothing but completely incapable themes! Sadly, my php knowledge is below zero so I’ve no idea how to make one. All I can do is adjust an existing theme here T_T. So please, PLEASE, can anyone tell me where I can find a decent wordpress theme for this use? I want a blog, preferably with three columns and above those columns an ‘About’, but most importantly one where the author is mentioned in the blog post and where you can click the name so I can make author pages as well? Plugins and other tips are welcome as well :). I’m so frustrated!
