Balvinder, I think I need to allow a reader that focusses on Training/Facilitation to comment, with a view toward what you are in search of.
My perspective is that you would not be in a position to need other materials, unless you are working totally from the ground up, as you would have some learnings to inject into the training program that needs to be implemented--based on experience, and not reference material. Is this totally new ground for you or is it just for supplemental content, I don't know.
But this is where we need to watch for responses from those who focus on Training.
Sorry if my initial answer as well as this one lead you down the wrong path, but I will watch with you for replies that are in tune with your goals.
