I also have noticed a lot of people, maybe 5-10% of my hits per day, are coming in through google searches for K99/R00 information. That makes me happy, and I hope the guide helps you all write your proposals!
I plan to write up a companion guide for transitioning once I get to that stage. In the meantime, I am still waiting for my award to actually officially START so all I can say for that part is to reiterate that you should make sure you keep in phone contact with the people handling your application. They are your lifelines.
