Just thought I'd weigh in -
My son is EBF but I would definitely have struggled to keep breastfeeding going if I hadn't have bought bottles and a basic manual pump (Avent, I heard Medela is also good) because DS was unable to latch on for a couple of weeks (tongue tie, birth trauma and inverted nipples here!). The hospital had me purely hand expressing like a wally and life was so much easier to get home and use the pump.
(I know you said that you weren't desperate to BF, but the expressing stage for me was just a minor blip really).
I bought a cheap changing mat but I don't use it very often because it always seems more convenient to change him on a towel on the end of our bed. He looks (and acts, less tears!) more comfy there as well.
Get loads of pads. I just got a pack of maternity pads but as soon as I got home went off to get several big bags of affordable maxi pads - highest absorbancy I could find (you will need it in the early days).
I bought a box of 74 size one nappies and a box of 74 size two. I didn't want to get too many in case he got nappy rash with the brand I got. I got Pampers, which I haven't had any problems with at all. I like the colour changing line!
I got a load of blankets, thinking I would swaddle, but in the end DS always kicked and punched his way out, he didn't really like having his arms restricted and I ended up using sleeping bags which we are still getting on well with.
I used the bathroom sink for a newborn bath! Much easier to fill/empty and no need to store. You can always get a foam insert, I got one just in case but DS was quite happy without so I just kept it basic.
I got flannels and sponges, DS prefers sponges - more gentle I suppose.
I got a couple of those little hooded baby towels but gave up on them after a little while. Although he likes being in a nice warm bath he doesn't like getting out into the cold so it's much better to have a big adult sized towel.
Two must haves I would suggest are:
Waterwipes. They are basically water and cotton wool in wipe form - they are the only ingredients plus a drop of fruit extract. They make things much, much easier in my opinion than using actual water and cotton wool in the newborn stage.
Somewhere comfy to plonk the baby down when you want/need your hands free. I use my breastfeeding pillow which works as a little nest/seat next to me on the couch and a bouncy chair everywhere else. The bouncy chair has come in particularly useful for putting in the bathroom while I'm trying to have a shower or go to the loo.
