So I came across this site (http://www.infoq.com/) recently. It has lots of industry news, but more importantly has a free eBook "Visual Studio Tips and Tricks" http://www.infoq.com/minibooks/vsnettt. You have to sign up to download, so spam might be a small price to pay 
I pride myself in knowing lots of VS shortcuts and the like, but I have to admit I have already picked up quite a few new ones.
