"Starter" Books and Videos?

I am just starting to dive into portrait painting. After a little research on the net, (mainly this site and particularly these forums), I bought Sanden's "Portraits from Life in 29 Steps" book and have started working through it. Any thoughts on this one and any other recs on favorites? Also, in favorites from video demonstrations? I have been oil painting off and on for 4 years, but drawing is my strength. I also just wanted to say thanks to the folks who post here, I think it is incredibly generous.

Thanks,
Matt Terhune
