Lots to learn......
Here's a few things I picked up over the past 5yrs and 2 boys:
-relax and enjoy the ride
-Holding them is a breeze. I, like you, had never held a baby before-never cared to. Support the head as their neck muscles are weak at first but they won't shatter like their made of glass so relax, you're not going to hurt him/her unless you're especially stupid/careless.
-be patient and understanding. As an infant their only means of communicating is crying. That means hungry=cry, got gas= cry, confused or overwhelmed=cry, just in a bad mood=cry. There will be times where they just need to cry in a room by themselves. If you know they are fed, clean and not genuinely in need of something letting them cry in a room by themselves is OK, it's NOT child abuse. The crying can be stressful (it was for me) and letting them let it out in another room gives you a chance to take a deep breath and relax. If you're angry and stressed it stresses them too and they crying will last longer. Trust me, you will need this from time to time. This is especially hard to learn w/ the first kid as you want to meet their every need immediately. Just don't ever handle a baby in anger. It is ALWAYS better to set them down in a safe (emphasis on "safe" ) place and come back when you've cooled down.
-you won't need to know about discipline until much later so don't sweat that. When that time comes though, don't be timid about setting the rules and enforcing them. YOU are the boss, make sure they know that. Keep in mind, not all kids respond to spanking. Be creative in your punishments and find what REALLY drives the point home with them. My oldest HATES being isolated and ignored. It's pure torture to him. He'd 10x rather be spanked so you can guess what his punishment is for major infractions.
-Never be afraid or embarrassed to let out your "inner child". Acting silly and playing stupid games is primo bonding time between Dad and kid.
-Never be afraid or embarrassed to love on your kids (even in public). A hug, a kiss, or an "I love you" can mean the world to a kid. It's important that they know that you love and support them no matter what and no matter who's looking. Tough guys can still be tough while loving their kids.
-lastly: in the whole history of the world there has never been a perfect parent. You will be no different. You WILL make mistakes. Don't sweat it. As long as you cover the major objectives (Love them, care for them, be there for them) that's all they will remember when their older and things will work out fine.
Good luck and enjoy what will be the greatest experiance of your life.
