Using Firebug (Firefox extension, great for web design), adding the good ol' "margin-left:auto;margin-right:auto" to your body did the trick for centering the content, albeit you may need to add a "text-align:center" to it as well for it to work in IE.
(which means all your contained elements need to set the text justification back to left)
The background-repeat needs to be set to repeat-x also to fit with that.
Never used the NVU editor as I'm more of a code-in-notepad person here, unsure how friendly it is with letting you actually putting stuff in yourself.
Overall, looks good, my main niggle is that the page feels small though on my 1280x1024 display, and the column's headers needs to be brightened up just a smidge imo.
