I would suggest doing more contextual linking. For example the pages you want to rank higher need to have links back to them in product descriptions if you want pads to rank than in other places on your site that mention pads you need to link those words to the pads page you want to rank. Also I'm sure your aware of needing more backlinks and make sure they relate to your site.
Good site with page rank 3 Google index : 149 results Yahoo : 189 indexed Yahoo backlinks: 908 indexed Google backlinks : 8 links
I have visited your site is good one, nice work done you have good number of quality back-links and no dropped domain. Cheers
