First off, say "Yippee!" She has said that she wants to try. These are the words that all LBS want to hear. Take a time out and just be happy about where you are at for the moment, as compared to two nights ago.
I don't have much else advice, as I haven't been in your place yet...I agree that you will need to take it slow and cautious; things are good right now, but it is hard to tell how stable it is. I have seen posts on here about what to do when the WAS has a renewed interest in trying, find those and read them. Follow what was on your notepad, that showed that you are getting it, and follow her lead as to how much pressure to put on her with the R. Good luck!
