The "About Us" page isn`t about you...it`s about how to contact you, and what`ll happen with orders and stuff. That should go to a "Contact Us" page, or on the "Email Us" tab. The "About Us" page, I think is very useful and few people work it well.
It`s a page that begins to make the business more human. Instead of reading a magazine online, or just a complicated brochure, the "About Us" page is a friendly way to chat up the customer, talk a bit about why the business exists, and what sort of people are alive behind the images on a machine.
The home page should have some content that explains why the person is viewing the site. It can have SOME product examples, but I`d rather see a "Products" tab on the main menu. Below that could be "Browse" or Search or whatever has to do with finding actual merchandise.
For example, you could put your paragraph that`s currently at the bottom, "At WebDuStuff.com we offer...." up at the top of the main page. Expand on it a bit, maybe two or three paragraphs.
I too didn`t care for the white on gray. And the bubble help is redundant; it serves no purpose.
The "Reasons to shop from (should be "with") us" makes no sense at all. There aren`t any reasons, it isn`t a link, and seems like a heading that goes nowhere. Make it a link, then put a list of actual reasons why someone should shop with you.
