1. No need for a detail cleaning. Just field strip the pistol and clean it. This is explained in your Glock manual.
2. You should not detail strip the weapon yourself as this will void your warranty unless you are a certified Glock armorer.
3. I am sure there are many good books out there but I normally stay away from gun books as I find most of them to be so poorly written it annoys me and I cannot finish the book. This forum is a great resource for information and I am sure someone will have a good book in mind for you.
Congrats on the new Glock. The 17 is a great pistol and should serve you well for many years to come.
