This already is a nice template. Plain text that responds well to zooming by the user; default colors that are easy to read and make links obvious; a few important images that are large enough to see, but don't take up half the screen like some sites' banners. If you prefer white-on-black text and have a user stylesheet for it (which I do), the site responds well to that too, without any nested <div>s or background-image:s complicating things (unlike some). I don't think that HTML5 web fonts or a whitespace-heavy designer template would aid in conveying any of the brief and well-organized information on the page.

(The only thing I would add to either of those is this bit of CSS: body{max-width:900px;margin:0 auto;} to make it easier to read on wide screens.)
