Nice header graphic, nice choice of blues.
However I would add a better contrasting color for text highlights, the red clashes bigtime with the blue. Maybe orange, yellow, or greens. The color of the contrast on the Site News graphic works very well, i would also make the titles of the plans on the right with the dark shaded colors the same orange hue.
There are a few pixels on the right menu where it does not align perfectly, between that and the header graphic.

i would download some of their free icons and use them to replace the current ones under the cp ad.
Just for business purposes, "Site News" is not the most professional, it has its places, but on a business site where you are selling a product or service, it is better to reserver that to a smaller area and use more of you content to sell your product/service. the space would be much better used for selling than for meaningless text, that frankly is too much too read.
If my purpose is to visit to purchase hosting accounts, i wouldnt waste my time reading that stuff. give people visual stimuli to focus on and appeal to the eyes with.
Some good stock photo will help you out.
Maybe develop a symbol, or logo for the header with some sort of contrasting orange/whatever hue you choose.
It is very nice however, just a little rough on the edges and fine points.
