anybody got kids, past or present i got questions

First you need to love them and not be afraid to show it! Diet is important as I see lots of this in kids who get too much processed sugar products. I teach martial arts to students young and old and find that if you discipline them firmly and fairly they will respect you. You may have to spank at first, but caution that if you do it do not do it because " you have had enough". One good swat should be all that it takes and it is best given with a good hug and reminder of your love after, you should not spank to hurt it is wrong and ineffective. I find that if I spell out the rules clearly and stick to them consistently I have the best results. finally you need to discuss with your wife and back each other up 100%, counting to ten really can help you when they get on your nerves as well. Good luck, this is one of the most important things you will do in your life, take the time to do it well.
