Hi Bertie - not long to go now, how exciting!
Personally I'd just by a stack of baby wipes for messy nappy changes and maybe 1 thing of baby bath stuff and leave it at that. I got soooooooo much baby lotion/bath/oil stuff as gifts that I don't think I will need to buy anything for at least 5 years! And anyway in the hospital they suggested just bathing with water, they said no soap stuff is needed and that it is all pretty much a money making machine and that's it. I do use baby oil a bit though to rub on Lucie's skin if it's a bit on the dry side after she's had a bath.
