If you have already read DR then I don't think you will get much new out of DB. IMO, DR is basically an updated version of DB that goes into more detail.
It sounds like you have a lot of positives in your sitch. Good luck! If you are already reading DR then that's a great start. I only wish I would have read it that early in my own sitch.
