First thing that jumped out at me was that $pages_query had no mysql_query() but you were doing $pages = ceil(mysql_result($pages_query, 0)/$per_page);

Other than that, I think your whole $pages_query is unnecessary. I think you can use LIMIT in your second query and it will skip the first n results.
