I really like the over all design, but I have a few issues:
First, the navigation could easily be turned into an unordered list and then the logo displayed as a centered non-repeting background for that list. There would need to be some tweaking (i.e., the gap between the third and fourth nav item for the logo), but I do think it would improve the semantics.
Second, you've gone with restricted heights on some of the context "boxes." For example, the "third row" the text flows outside of the box after only one text size increase (I'm on mozilla, this wouldn't happen in IE of course). I can understand your desire for a pixel perfect layout (especially in this case where you wish for the content box to be the same size as the image to the left), but some times there needs to be a little sacrificing. Other than that top box, I see no reason to why you would need fixed height boxes anywhere else.
Third, once you get to the main content area, you've used paragraphs to styling everything. Interesting enough, you've given some of your paragraphs classes such as "newsHeader". Why not use an actually heading tag here as would be most appropriate. For instace, the date could be enclosed in <h3> tags while the heading could be enclosed in <h2> tags. This would make the code much easier to update and much simpler. Now you can just use flat out <h
n> tags and <p> tags and not worry about extraneous classes.
Other than that, that's about all I got. Very nice looking site overall, just a few tweaks under the hood would make it really great!
