You probably have your bases covered with diapers, wipes, formula, bottles, clothes.
What you'll really need is patience for the first few weeks, your life is going to change dramaticly but you will get used to it after awile. Sleep when your baby sleeps if that's possible, don't expect him/her to follow your schedule :), you need to follow their's.
Remember a baby can't do anything for itself, you and your wife are it's sole provider, of course you'd be pissed if you couldn't tell anyone what's wrong! he/she will cry for anything & everything, try to understand what they are crying for sooner than later, it helps a ton! My 3 month old will stick out her tounge if she's hungry, pout when she's tired and just want to be held and rocked until she falls asleep.
After a few months they'll sleep through the night (if your lucky), and things will get better, hang in there and enjoy parenthood. Oh, and don't forget to take as many pictures / videos as you can, they grow up soo fast it's nuts, mine is already twice her birth size.
