First, I’d recommend using a spam filter like Akismet to prevent spam comments ??

Second, the answer you seek is (hopefully) in the comments.php file that’s part of your site’s theme. For my theme, all I’d have to do is move one section before the other and .. tada! If this doesn’t help you, feel free to post a reply here, and I’ll see what I can do!
