The cosmo pregnancy mags have a really good checklist of things required and then theings optional for each area (babies room, bathroom, car, out and about, kitchen, etc) I found it really useful.
I am also a first timer making my way through the list of must haves - just wanted to suggest the babies galore catalogue as a helpful place to start - their list is really comprehensive (a little daunting) but there is a lot of info in there we picked one up in store. Target and Big W also have lists up in the baby sections of their stores and i think you can download and print them from their websites as well.
Its so easy to go overboard when prepping for the Baby's arrival(I literally couldnt stop myself buying 000 clothes!) I would say
Car seat
Pram or Sling(I used a sling until DD was about 2 months old)
Cot(She didnt go in it untill around 3 months)
Nappiesx a million!
Wipesx heaps!
Facewashersx 10 or so
Singletsx 6
Jumpsuits x 6
socksx 4
muslinsx 6
Thats about all I can think of, people love to buy for babies too so if you are having a shower you will get heaps of this stuff.
