I'd suggest looking at SEO forums for more focused advice.
As a guide;
-Watch out for keyword stuffing (ie repeating the same keywords again and again). You'll probably have it in your product name and description.
-The SEO description will be seen by humans, so make sure it clearly says what is on the page. Keep it fairly short
-The SEO page title should also contains alternate spellings/names of the product
Make sure the product description (ie in the product set-up, not SEO) actually describes the product. If you were to read this text to someone over the phone (or post in a forum) without them knowing what you're selling... could the work out what the product is, and what it does?
Google etc won't understand what the picture is showing, so you have to help it with a good meaningful description.
Also, its worth adding a link to your CubeCart site on this forum (in your signature). Non-cubecart sites are removed (so don't add anything other that your website).
I hope this is helps,
