Good looking design. Just a few things..
The inclusion of the skip to content thing makes no sense to me. There isn't much of a fold in the site and the rollover appears each time I move my mouse to the URL bar which is quite annoying. An image linking to the site content would suffice if you wanted to make the site more accessible.
I think more consistency on font and font colour is needed too. The badges for each type of hosting look odd for example. The heading colour is blue and underlined while the other similarly styled headers (domains / hosting / account / support) are white and not underlined. I think the blue headers would like nicer white. The two buttons on the bottom of each of the badges would look nicer if they were white and bolded too in my opinion.

http://www.blacknightvps.com/fileadm...simple-bg2.png doesn't fit right for me either. It looks odd having green bubbles so close to the black bubbles, especially when the green ones aren't properly visible. I would probably remove the magnifying glass and increase the size of the search box as it is quite small as things stand.
Not sure what the significance of a meta tag generator is in relation to VPS solutions.
More content is required about VPS (what it is / differences between packages / etc) as was previously mentioned.
The site is slightly broken in Safari 3 on OSX too. I can see speech bubbles and some overlapping.
