I didn't have my dad in the home, so I can tell you first hand that not having a complete family sucks and it certainly affects the development of the child.
From what I read here you are on the right track to be a wonderful dad, not only because the proper family structure you guys have, but because of the proper mindset you are developing right now.
Informing yourself and learning about all the skills you need to provide a good parenting for your kid is not something that happens overnight. It is very wise what you are doing and I bet everything will turn out great.
Cheers mate.
