My DS is only 16 days old so speaking from very current experience...!
Sleepyhead is a godsend- DS has slept well in it since we brought him home from hospital for around 3 hours at a time, whereas he will only catnap in the Moses basket downstairs. I'm caveating this though by saying he's a big baby so may just sleep well anyway.
Snuzpod / next to me: not needed, but just check that your Moses basket will fit the Sleepyhead if you decide to get one. Most don't, so we bought a zip'n'go crib which converts into a travel cot / playpen for when he's older rather than an expensive crib.
Breastpump: I'll go against the curve here and say it's worth getting one from the start, but try renting it. DS wouldn't latch and I ended up with blood blisters on both nipples by day 3. The pump let me give them time to heal whilst still ensuring my son could have breast milk. If you decide to buy, I bought the lansinoh double pump which is a third of the price of a Medela and worked really well.
Ewan: don't need one, we found an 8 hour white noise video on YouTube which we leave playing overnight (thank god for unlimited data plans though!). Ewan is also a popular gift to give.
Video: we have one which is already useful as I put DS in his crib in our bedroom from 6pm so he makes the day/night association early. We check on him regularly, but the video is additional reassurance and means we can still have some time as a couple in the evening!
Other things we've found amazingly useful from the start are a changing table (I know lots of people say you can change them on the floor but bending and lifting post CS was impossible) and more muslins than you can imagine. Don't buy more than one baby towel or blanket as EVERYONE will give you these as gifts.
