RE: training pups
I like James B Spencer's Retriever Training for Meadows and Marshland. I also like the tapes and books by George Hicoxx. I love Mike Pinds tapes, but they are slightly out dated. Find a program you can live with and go for it. Your library might have some training tapes. Labs are the most popular breed so many librarians do stock an assortment of books and tapes.

PS Don't discount Spencer's Hup. Even though it's spaniel training all info can be used to train an excellent retriever.
