Hey Glenn,
A bunch of things come to mind.
I don't know what style you're into, but here are some suggestions for lead stuff...
If you're into fast lead playing, like metal, there are a bunch of lead tutorials by Ben Lindholm. He's kind of on the "nutty advanced end" of the shred spectrum. If you scroll down you'll see a section under him called Focus On Lead Playing.

Dave Celentano has a large variety... he did a bunch of Artist Studies, like Randy Rhoads, Eddie Van Halen, Joe Perry, Stevie Ray Vaughan:

And of course Christopher Schlegel has a giant library of content, too. If you scroll down on his page you'll see "Learning Blues Licks" and Sweep Picking, Building Speed, Improvisation, etc:
