I want to give few answers for your questions. I have already done some of following tasks for my website. But, still not getting... That's why I am too much irritated with it.
1. Have you submitted a sitemap to Google? If not, do so as there are clearly some issues.
My answer: Yup, I have submitted to Google, Yahoo & Bing.
2. Have you performed a test crawl of your site? Use the SEOmoz crawler. You don't need a 100% complete report. You are trying to review your site for crawl errors which impact your whole site.
My answer: Yup, I have checked it. You can find out attachment to know more about it. You can help me more on this section. Because, I am quite new with SEOmoz tools.
3. I would suggest examining your site's navigation. With only 1% of your site getting indexed, there may be a problem.
My answer: Regarding what? Top navigation? Left navigation? Footer? Breadcrumb or HTML sitemap?
4. Do you have any content on your product pages? If you just throw up an image with a product name, the page will likely not be indexed.
My answer: You can look in to know more.

I have added all product details, manufacturer details (But, it's duplicate on many webpages.)
5. Ensure your robots.txt file is not blocking pages which should be indexed.
My answer: Yup, I checked it ... http://www.vistastores.com/robots.txt.... It's perfect... according to my opinion... 
6. Thoroughly examine your Google WMT for errors and issues.
My answer: I will do it... It's remaining.
