I agree with Mite on the Rick Smith method for your dog. I utilize it to train my dog (also a pointer and my first dog). Rick's method builds off of his dads (Delmar) and he offers seminars all over the country to help you in better understanding his approach. Here is a link to his website for information on his videos/DVD's and seminar schedule.

I disagree with Mite though in that the method is only for pointers. I've gone to 2 seminars and there was a mix of both types of dogs (flushers and pointers). It is a common sense approach to dog training that utilizes sound building blocks that anybody can do. I highly recommend it and wish you the best of luck with whatever you choose.
One more thing. Although Wolters book is the old stand by, I would
not read it in a literal sense. His book is based on what a dog should be able to do by a certain point in a dogs life. I've seen first hand several people who have been overly hard on their dogs because the dog couldn't do what Wolters said it should do by a certain age. Each dog is different and so is it's development. Be patient! Some dogs mature faster than others, even within the same breed. Be patient with your dog for at a
minimum the first year before you raise your expectations to the level of "a finished gun dog".
Here is a really good book that I read that also helped me with my dog for it's first year.
"How to Help Gun Dogs Train Themselves" by Joan Bailey
