Well, I haven't had the baby yet, so my advice probably isn't really helpful.
If you're looking at baby carriers (Snugli, BabyBjorn, etc), go to Babies R Us and try them on. We were planning on getting a Snugli until we found out it wouldn't fit my husband, and wasn't too comfy on me. We ended up getting a Kelty Kangaroo off Ebay - fits both of us really well.
As far as diapers, we have a few packages of the newborn ones, and after that, I'm planning on using cloth diapers. So we bought a bunch of different ones, but I shouldn't need to buy diapers again for a few months.
Definitely yard sale and see what other friends who had kids recently have for leftovers. We got our baby swing from a friend, and pack n play from a cousin.
Other than that, we're planning on seeing how this goes, and then picking up stuff as we find we need it.
