You should look into rewriting some of your title tags.
You're going for genric words which high levels of competetion, also look at (if possible) putting better title tags on your product sections.
People will rarely search for "r101" but may be more inclined to search for something like "onxy and crystal ring".
See if you can expand the product description to include some of your keywords, just don't make it too spammy.
It's good to see you have Google Analytics installed on your site. It's an important tool in tracking who your visitors are and what they do.
