Welcome to fatherhood! You won't understand this fully for a month or so, but you are disembarking the express train to Hell. My wife and I are wishing you guys all the best!
On a side note, if you want to do something simple that will have a POWERFUL, lifelong positive effect on your child, I strongly recommend you practice kangaroo care as often as possible after the birth. It's catching on, and some wards will encourage and facilitate it, but it's really up to you two! In a quiet room, take your new little ruffian/princess/Chosen One in just a diaper and lay them on your bare chest. Mothers will often do this, especially those that are breast-feeding (which should be the case, exclusively, all things being equal), but there are so many reasons for Dads to do it as well. There is simply no substitute for the bonding and health benefits that arise from kanga-care.

Much love and have fun- you only get to go through it once! (The first one, anyway).
Feel free to PM me if you have any questions or issues.
