Definitely check there^ good call graham.
Troy Stetina, and his Mechanics of Speed Picking book, and vid is essential. Daryl Gabel has some cool stuff, and also, there are a lot of songs tabbed at Powertab, that have speed passages that you can learn.
My advice? Learn to walk, before you run. Take your time learning fundamental scales, and patterns, and be able to play them competently before you just jump into the high speed stuff.
