To give you a resource for html5, I offer the html5doctor - where you'll also find a version of the javascript shiv mentioned earlier. (There are several versions out and about.)

For a discussion as to why html5, if you're interested in deploying your site(s) on mobile devices, you might want to read Mac Slocum's interview with Eric Meyer on O'Reilly Radar, in March this year. (I'm not permitted to cite the URL for you but it has to do with "why html5 is worth your time".)

On my sites, I found html5 to provide a great benefit to me *and* the visitors (win-win) by enforcing upon me a more strict organization, decreasing code bloat, and opening the door to easier mobile testing.
