Help me find the ideal theme! (Sport/Interviews)

Hello everyone,

I have just started a new website project that I would like to do with Word Press. I have very little experience there thus I would like to buy a ”ready to use” and flexible WP theme.
But I am struggling to find something that I like. The basic idea is to have a website full of interviews of people in the ”Sport” world, probably mainly in football (soccer I mean :))

A main page with links to my Facebook/Twitter accounts, easy to scroll down, tabs divided per country/sport/language/etc., SEO friendly (that is very important I guess!), Facebook comments for each interview page … Well, nothing too complicated!

Can any one make recommendations?
Also, where to find themes? I know of ThemeForest, is that the best Theme website around?

Thank you in advance and cheers from Argentina!
