Don't give up on that dog! by Denine Phillips - The book is in diary form and a bit dry, some of it boring, but it what one would typically go through raising a GSD puppy. At the end of every chapter are "lessons learned" which are filled with valuable information.
The other book which is very short and for all breeds is, On talking terms with Dogs: Calming signals by Turid Rugaas. It great for my daughter and I to be able to read our dog's body language.
These books are not really about training as you wished, but understanding the breed and dogs in general. Good foundational books.
Oh, and here's a link to a website (our breeder) for basic hand commands and commands in other languages, if you want to get started early: http://www.vonfalconer.com/commands.html
