I'd indent your left column items a little more. The stars rub against the border considerably compared with the arrowed list below it. I also wonder if the images under "Select the Type of Credit Card You are Interested in...." (you may want to change 'in....' to 'in ...') should be aligned left so they look more like what you're doing in your header.
At 800 x 600 a site should not produce a horizontal scroll bar. Your site does and it appears (as in, what the eyes see) to be for the benefit of the vertical gray bar on the left, not for the content. Rework the layout or just make it a tad thinner.
