I will agree with the idea of some sort of baby carrier. Neither daughter liked the sling as a newborn, but they both loved the Infantino soft front carrier. You can use the bucket out of your infant car seat, but it made no sense to me to add an extra 10 - 15 pounds of weight to carry.
I also agree on the blanket thing, though most of our blankets weren't flannel, just cotton recieving blankets from Gerber or Carter's. Both daughters, especially Linda, nursed much better swaddled; in fact with Linda we had to swaddle her before she would nurse for the first couple of months. They slept swaddled too. The Baby Book by William & Martha Sears is pretty much the attachment parenting handbook (I bought it because it was the thickest one in the store. :LOL), & has great sections on swaddling & breastfeeding. The other book I have that I've used for both children is Your Baby's First Year Week-by-Week. Helps alleviate a lot of the "is this normal" questions, but it's not something you *need* by any means.
I never got out birth announcements, because I was never feeling energetic enough to make them after the baby was born, so if you want to do those, the advice to get them as much as posssible done now is excellent.
