How about a short list of things you don't need even though the baby industry says you do? You do not need a changing table! It takes up space and is useless after the baby is out of diapers, and most are too rickety for changing a toddler's diaper, so you'll stop using it sooner than you think. Don't bother with these things -- change the baby on the floor (when wiggly) or on a bed (when very small, and with a good waterproof changing pad). The money you put into that useless changing table can be better spent on both disposable pads and a few good, washable changing pads!
You also do not need a "baby wipe warmer." What a total scam. I know one mom who felt that using warm wipes meant her son stayed asleep through nighttime changes better since a cold wipe might have woken him but still -- to me it's a waste of money on something you won't need for long.
You do not need crib bumpers. These have been shown to be a suffocation hazard just like all other soft bedding, which infants do not need to be comfortable. Several different crib bumpers have been recalled by the Consumer Product Safety Commission as entaglement (read: strangling) hazards (go to cpsc.gov and search "crib bumpers"). And you do not need a matching comforter/bumper/pillow/ etc. set. They're pretty and utterly useless because infants do not use pillows or comforters at all because of the suffocation hazard. Spend that money on something more useful.
You do not need a "walker" since these encourage infants who are too young to control their movements well to scoot around --and down the stairs, and over a threshold that tips them, and so on. Dangerous. You may like instead to get a "baby bouncer" that just vibrates and gently bounces the baby but does not GO anywhere.
You DO need a good diaper bag but it does not have to be expensive. Look for one with a totally waterproof inside (to contain spills of a bottle or leaks from a container of wet wipes) and be sure you can live with the design or color for two or more years. I would hate to be stuck with some nauseating color or pattern that's too babyish and screamed "New mom" all the time. I found one that was black and looked like a purse.
Basically, keep it simple. Don't load up the nursery with stuff that is going to be useless in a year to two years. Don't be afraid to change a diaper wherever, or to use a wipe straight from the box, or to say, "We don't need that Pooh patterned comforter set just because we have a Pooh nightlight." What you really need are a few outfits, a couple of good swaddling blankets, whatever feeding system you need if you're bottle-feeding, and a high quality and safe crib (no hand-me-downs, NO drop-sides which are no longer considered safe). And be sure to get good, well-fitted sheets for the crib so they do not pop off the corners, which is another strangulation hazard. Invest in good quality sheets. That's it.
