Congratulations on the new adventure.
I have to echo the suggestions for the combo stroller/car seat/bassinet, it is a life saver (usually yours).
We ended up using a Baby Bjorn as our son just did not like the sling, so you may not have the decision making power for that one.
Breast feeding has numerous advantages for the baby but my wife also said it helped her shed those extra birthing pounds a lot faster. It can be a pain though if the little one then turns up their nose at bottle feedings.
Don't be fooled into thinking you need a changing table, ours received minimal use as we usually just used a bed or couch.
Get a bigger vehicle!
