The first thing I see is something I am doing with this one. I am not using wool soakers until they get past that "poop every time they nurse" stage. You will be needing to do a LOT of handwashing those early days if you have a bunch of wool soakers because those early poops are messy and frequent and almost always hit the covers. I would get a few nylon or plu covers for the earliest days. The brand we liked best with our last one was Bumpy, but I will probalby get some Bumpkins for newborn since I remember them being more lightweight and breathable than prowraps and cheaper than Bumpy. (also, prowraps are better for skinny legs, imse vimse Bumpy are better for chunky legs)
You might add some wool care to your list...like Euclen. Also, things like baby oil (we love Burt Bees here), tea tree oil, baby wash/shampoo
Another sort of weird thing is a fleece blanket. If you don't put covers on them all the time, it is nice to have a fleece barrier between them and your clothes. (a friend of mine is making me some fleece pillowcases to stuff with a prefold for this purpose) Also, if you have a diaper leak in bed, a fleece blanked over the puddle will allow everybody to go back to sleep without having to redo the entire bed.
Also, those first months go by FAST...you might also ask for things that you will need down the line a bit. (clothing, dipes) Do you have equiptment to make baby food easily (obviously, you can just use a fork to smush things up, but a hand blender or strainer is nice too)
You will find that you either love or hate onesies. If your baby is long waisted, they are almost pointless, especially if you cloth diaper. Also, they tend to wick from the diapers more than any other clothing type and need to be changed each time, and are one of the more difficult items to change on a floppy infant. However, they are easy one peice dressing if you don't feel like putting pants on them.
Congrats! I think I might be copying your idea if you don't mind.
