If you are unsure of what all this would entail then as with any business, it requires research: fortunately there are plenty of pet trade magazines and website that can help with this side of things.
Dogs are naturally sociable animals; their understanding of their world is based upon a social position within a hierarchical pack. Some dogs are dominant, others will be submissive and both will behave according to its position. Your family group is basically a pack scenario to Fido. Whilst you really don't want him to be top dog, nor do you want him to be so submissive that he spontaneous urinates to try and grovel for you. In this latter scenario Fido's confidence is definitely requiring a boost!
