What template does classifieds use and permalink?

Hi,

Looking at an individual post looks ok but when looking at the main classifiedsn at
http://www.worldcollectorsnet.com/classifieds
The page looks terrible.
We have a custom theme that works in BuddyPress but cannot see where the classifieds gets its template.

An example product can be seen at

Also how do you change the permalink of the classified ad itself to /domain.com/classified/.....

Thanks

Darryl
