looks like you've got lots of great suggestions already! Only thing I wondered about is how far apart the 2 boys are... the market is being constantly bombarded with new products for infants and little ones that can really help simplify life for new moms and/or aid in devopment of the little ones...
Diapers are always a good one, the new genie's are nice too though... one of my favorite products were Medella's microwaveable sanitizing bags... DH and I have lots of out of state relatives and it was nice to be able to only take a coulple of bottles with us and know we could sanitize them on the go without boiling water or a dishwasher- found them at Target...
Also a huge fan of disposable bibs and sticky placemats for dinning out...
