I'm not a by-the-book kind of person but what I will recommend is working on your marriage. If you and your spouse are of the same page regarding everything and have resolved to live lovingly and help one another to heaven, then chances are you will be on the same page regarding discipline, education, and all the other aspects of parenting. It really is so essential to have a smooth running marriage, it puts everything else right regarding children.
They key with discipline is to do it with love and to be consistent. I don't think a whole book is necessary if you can get those principles down, you should be all set.
In addition, family rosary, every day, without exception. I've never known a bad parent who prayed the rosary with their children every day, and I've never known a tremendously good parent who neglected to pray the family rosary.
