To keep it simple?
The complete idiot's guide to Poodles. It is a simple read, and covers all the basics and tells you where to look for more info on any subject. Tells you how to find a good breeder, get in contact with a rescue, food, training, health, grooming, you name it. Just don't let it spook you; they give the best and the worst case, so you will fully understand what you are doing.
Tell your Dad CONGRATS from me. They are so smart, loving, and have so much personality, they are almost human. I am sure he is going to love his new best friend.
