Congrats, Eph. She's a beautiful baby.
I'm a mommy to two girls (ages 3 and 5). It's been interesting reading this thread and getting some of the Daddy perspective.
How's it going now? What's your routine like? I'm about to hire a "mother's helper" (sexist, I know), as I can't possibly do all the household duties on a day to day level (I take care of the financial/administrative/legal matters though); I really hope that helps ease some of the stress we face with trying to get so much done. Of course, I will still make the Costco runs-- I won't give that up.
Mother's Helper? I didn't know they had such things. Gosh, that would have been great. If you can afford it, by all means, go for it.
As for the household duties, though, you could just accept that some things don't/won't get done like they used to. But face it, your "household" isn't what it used to be either. You have an extra person to feed, clothe and bathe.
You'll probably get lots of advice, especially from in-laws

...but we've found the most useful tips come from within our peer group from those who have children just slightly older than ours. They actually remember what it's like to go through certain phases and don't have the convenient memory-loss that grandparents tend to have.
And so, for what it worth, I'll pass along the two best pieces of advice we've received:
(1) Let sleeping babies sleep (as long as the sun isn't up). The hospitals and docs make a big to-do over waking them up to feed them. BS, I say. And you've already found it out. She will let you know when she's hungry (hurt, dirty or tired).
Vandre is right; when you get that first 4-6 hr night, many things change.
(2) No one will know your child like you will. If you're torn with how to handle a situation, discuss it with whoever you like, but in the end, it's your (and your wife's) decision so go with your gut.
And to those who say "enjoy this time while you have it, it goes by so quick." Well, they're right...but I find myself still anxious to move on to the next phase, whatever that maybe. For us, for our oldest, it's teaching her how to read, write, tie her shoes and ride a bike. For the youngest, it's teaching her even more words and beefing her up so she can ditch the 5-pt harness car seat. Thankfully, we are already done with bottles, sippy cups, diapers, walking and talking.
You'll know you've reached true Daddy status, when you're rummaging around in your tennis bag...and pull out a (clean) diaper and wipes.
Best of luck to you, your wife and your beautiful little girl. Keep us posted on all your progress.
