Congrats at getting a dog, sorry to read the female didn't make it. Getting a puppy can be such an emotional experience. I am on my third dog for bird hunting, I am by no means an expert, but I have gone through a lot with my mutts.
In my opinion, you should read every book you can on labs and training dogs. Get lots of knowledge in you and different ideas and different approaches and different views. There are lots of great books out there. The already mentioned Wolters is a good read, but outdated. I also REALLY like "The Labrador Shooting Dog" buy Mike Gould. It is a great read. The Art of Raising a Puppy by The Monks of New Skete is also interesting.
Wrap your mind around using a electronic collar. Either you will, or you won't. Don't punish your dog later by "not" using it now and find out later that you want to. I highly recommend the proper use of an e-collar. We can go more into that later if you are struggling with it.
I would then decide on one of two programs. Smartworks or Training with Mike Lardy. And stick with the program. Don't use some of this and some of that. They are both well proven and fanatastic training devices. They are the only two I would recommend.
I would then try and find the book "How to Raise a Puppy You Can Live With" by Clarice Rutherford and David H. Neil . A another Great book on raising a pup.
After that, enjoy your new dog for the first year of it's life. (well hopefully for many years) Let it play and grow and teach it to become a good citizen. Start teaching obedience from the moment you bring him home but leave the discipline for later. Play fetch, let it follow you around, go swimming...Just don't push to hard to fast.
here's my two pride and joys, Diesel at 10 months and Cruiser at 6 years
