Since you're coming from an object oriented background, you may want to look into PEAR:
http://pear.php.net
and for PHP classes:
www.phpclasses.com
I have not explored it any great depth, but I have seen some people extoll how great it is.
For a pretty good PHP/MySQL intro, the Sitepoint website has a pretty good article. Actually, they have a lot of pretty good articles.
www.sitepoint.com
This may not necessarily help you with your specific project, but at least you have a few more resources available to you if you weren't already aware of them.
Hope this helped.
