You:
Breast pads
Nursing bras (or at least bigger bras!)
Antibacterial spray
Nipple cream
Make up
Hair brush
Baby:
Nappy cream
Misc:
Hospital notes
Birth plan
Change for machines (drinks, soup etc)
I didn't use half the stuff I took and you can always get someone to get you more stuff if you don't have enough, so seriously.. don't take too much of this crap you read about!! just the essentials.
Hope that helps
