Looing for a similar theme – or modification

I am looking for a theme which would match the two column style of BleedingCool.com. I would like one category feed (with pictures and brief description) on one side and a different category feed on the other (with pictures/description). Does anyone here know of a theme which will do this for me, or of a way to modify a theme to do this? I am currently using the GamePress theme. I am knew to the entire WordPress thing, so be nice ??
