Meta tag problem

When I view the source on my web site, my meta tags say this:

<meta name="keywords" content="Hickory Canes Oak Canes Cherry Canes Walnut Canes Accessories Pure Hickory Heart Hickory with Heart canes, walking canes, custom canes, hardwood canes, hickory canes, oak canes, cherry canes, walnut canes, " />
<meta name="description" content="Hardwood Canes - Hickory Canes Oak Canes Cherry Canes Walnut Canes Accessories Pure Hickory Heart Hickory with Heart canes, walking canes, custom canes, hardwood canes, hickory canes, oak canes, cherry canes, walnut canes," />

1. Do I have too many listed? It seems that products are being listed twice.
2. Shouldn't there be a comma "," in between the meta tags?
3. Where do I change this?

Thank you!
