SEO osCmax oscommerce Search Engine Optimization

Im in need of simple SEO for my website. Im running an osCommerce site with Basic Template System(BTS). I have a meta tags controller installed, so they can be played with easily. I need Search Engine Friendly URLs, for which I have a contribution if you would like to pop that in. It will need to be integrated with my current files. Also, Id like a list of other tasks that you can provide, or that should be done by us. This should be a fairly short job, we just need a tune up.
