With regards to your website, I too like the look of the site and it seems very easy to navigate, maybe add a roll-over colour to the left handside nav though. Not delved into your code so cannot comment although I don't see why it can't be W3C compliant as it seems pretty basic, you can sort the tables issue with CSS if you really wanted to.
I also like the font you have created so let us know when it is available...
