I have finally started diving into more HTML5 lately and have some good links to help get you started. The syntax itself is somewhat new, but the hard part in my opinion is knowing what browsers support what. The easy answer seems to be Chrome 5 supports the most, followed by Safari 5, then Firefox, and lastly Internet Explorer 8 (with almost no support, shocking!). I have moved to Chrome as my default browser now for quite a few months since it just supports so much more of the standards than the others.
The new syntax and tags make a lot of sense one you get the hang of it and see the reasoning behind it. The CSS3 and JavaScript enhancements are also pretty slick. Some of things MooTools offers are now integrated as native functionality. I still plan on using MooTools to ensure cross browser support though.
