I think you should stop and regroup.
Where are you now?
Search for your category pages:- I tried Olympic Queen Bedskirts
Number 34 & 35 on google UK
http://www.google.co.uk/search?q=Oly...&start=30&sa=N
Same with google.com
http://www.google.com/search?q=Olymp...&start=30&sa=N
Yahoo 7 & 8
http://search.yahoo.com/search?fr=ro...en%20Bedskirts
7 is your Create an Account page and 8 is your home page.
As far as yahoo is concerned for cetegory pages your onsite content isnt strong enough, keyword enrich a little and add another relevent sentance or too for each cetegory. I would change your internal linking for your non seo links that are on all pages to javascript so they detract from your seo.
Start building targeted links from other websites to your category pages, it wont take many to make a difference.
Item Pages:
Check your headers, you have no title or keywords.
Change Item Description to be the name of the item. The search engines will automatically read the next bit of text as the description.
I googled an item (Olympic Queen Ruffled Bed Skirt)
