excerpt text along with meta data and post title is all tangled up on

on the classifieds archive / categories page the excerpt along with the post title and author name and post categories are all mangled together, and there's absolutely no css to separate each of these very different post elements. this is unacceptable but I'm sure I'm missing something. Is there a template file somewhere where changes could be made to better present this post info?
