Great post, I've been doing pushups and pullups w/ no real rhyme or reason. Your post is timely for me, so I looked into it and it sounds great. I started the day of your post and have just completed my first week. I also looked on the web to see if I could find a program that is similar for pullups and found one that I've also just started. Check it out:

I'll also join you again posting in 6 week or so w/ results.
