59906 Install Affiliate Script

I would like to install this script: [login to view URL] on this site: http://emporium-one.com. After install lite modification in color for seamless look, as well as affiliate info links put on page....something like the lower right corner of this page where you see affiliate stuff...[login to view URL] I thought I might be able to do it but not sure about some of the "need to do's" of the script instructions. However, if you know of a better free mod made for oscommerce sites that are easier and better options please let me know as well. Thanks
