Which blog network theme would work?

I'm looking for a blog network theme that I should have as the first page on our network that I´m starting a setup for today. My wish is that I will be able to list all our bloggers with an avatar and blog description, view recent blog posts from members, show latest comments from all the blogs, display a global tag cloud, custom header, latest news. I have looked at "Network Theme" but I do not know how I'll get what I want in the best way and change the theme to suit us.

Looking forward many and quick replays. :slight_smile:
