To me it sounds as though he is trying to get rid of the URL parameters to clean it up for SEO purposes, rather than changing the names just to change them for the SEO aspect.

It is similar to wordpress - you can have it setup site.com/posts/post-title-goes-here instead of site.com/page.php?postid=184&this&that

And that is controlled use ModRewrite with apache if you are on a linux based box, and I have not a clue what the windows equivalent is for a url rewrite.
