I like it at the right. I don't see any reason why it can't be in the right. Could you give us a link to a W3C reference that says navigation bars should be in the left?
While I don't know of any clear recommendation to put a navigation bar not on the right side in my opinion it violates Jakob Nielsen's rule "Do the same as everyone else" (see #10 of "Ten Good Deeds in Web Design" at http://www.useit.com/alertbox/991003.html). There have been some links posted to websites that have the navigation on the right side. However I would rather follow the mainstream. Look at all the explorer-style windows in your operating system: Navigation is always on the top and on the left. If you really want to make an exception and put the navigation bar on the right side you need a strong reason to come up with something unusual.
Out of curiosity, have you experimented with the look of full justification for the text? At least for sentences that span multiple lines. I not a web designer, and like most other suggestions this is purely subjective, but I wonder if a subtly sharper edge on the right might further instruct one's eye to perform a carriage return/line feed?
