Forums Layout not very Clear with Studio Theme

I'm using the Studio Theme + the bbpress 2.0 plugin (Forums) ...

My Forums have a lot of categories AND sub-categories ... But the way they are displayed within the Studio Theme is not very clear for the end users ... (thats what they told me)
Have a look at the screen capture below ...

First, the category NAME is displayed, then in brackets the NUMBER OF POSTS, then a COMMA, and so on ... and so on ...

Also, the Main Category Description appears UNDER the sub categories (when you create many sub-cat it is not very clear ...)

Is there a way I can customize all of this ?
(I'm not a CSS expert)

Thank you.
