I've critiqued your list to help you save a ton of cash based on our experience.
Travel system:
pram
pushchair
car seat
fixer for car seat
All sounds about right
Bed:
moses basket
bednest - don't think you'll need a moses basket and a bednest.
cot bed
mattresses
sheets (4) - we got away with 2, but then I'm not a change at every dribble kind of person.
blankets
swaddling blankets - use a normal blanket for swaddling.
grobags
Furniture:
changing table - completely unecessary in my opinion
Curtains - just use what you've already got in the room then decorate at age 2/3 when they actually have interests/an opinnion.
chest of drawers - very useful, i'd go for the deep ikea ones.
toy box - a carboard box does the trick for us
rug - probably not necessary
nappy bin - just use a normal swing bin for £5
chair (rocking?) - we never used a chair
Clothes:
sleepsuits/babygros (7-10)
bodysuits/vests (7-10)
hats (2)
cardigans (2)
booties - just go with babybrows with feet in
bibs - useless until weaning and never used the million we had
mittens - get babygrows with inbuilt scratch mits
pram suit/fleecy all-in-one - good idea, but they're dangerous in carseats so for pram use only.
snow suit
padded jacket - didn't use one until DS was walking (18 months) snow suits much more practical.
socks - just use baby grows
Nappy bag:
nappies (3-4 packs)
cream
wipes -water wipes/wipes
nappy sacks
travel change mat
Feeding:
nipple cream-lansinoh
Breast pump
sterilising equipment
bottles
nipple shields - wait and see if you need them.
Bath:
Towel
Top and tail bowl - waste of money, just use a couple of different tupperware boxes.
Thermometer - useless, you'll soon get the right feel
Sponge - just use whatever you've already got
flannel
Cotton wool
Nail clippers - unecessary, their nails flake off for months
Brush
For mummy:
witchhazel, arnica, lavender oil
Vests
Cheap pants
maternity pads
feeding pillow
Misc:
Room thermometer - lots of monitors have this built in, so check before you buy.
Sensors: sound, video, movement?
Sling
Change mat (2) one is enough.
Baby gym/playmat
Chair(vibrating)/bouncer
muslins
