Okay, I've gone straight crazy. Maybe it's Baby Brain, or maybe it's just me!
I think I am going to start making my own diapers. Found some really great fabric (organic cotton/hemp blend, can be bought by the yard at Amazon or from wazoodle.com). The wazoodle website (Little Green Bear company) also has some great things, like sew it yourself kits! I don't know if I am reading this wrong, because it seems waaaaay too good to be true, but they have sew it yourself fitted diaper kits, organic bamboo, a dozen for under 4 bucks! Someone else please check this website and tell me I'm not seeing things. $4 and I get 12 completely cut out diaper bits (including the snaps) and all I have to do is spend some time sewing them? Yes please! I am not the biggest fan of bamboo (the process to get the bamboo fiber into fabric/yarn/thread/what have you is really intense, so I have read), but it is oh so soft and all natural for little baby bums.
I also found a great resource for making your own soakers/covers at http://katrinassqs.blogspot.com/2007/10/free-soaker-pattern.html
(forgive me if this has been mentioned already!)
Been searching for crocheted diaper covers as well. So I am on my way to making a ton of woolie soakers and organic cotton, possibly hemp combo prefolds and maybe even some fitted diapers.
Am I crazy? Yes, but this is what nesting is all about! And apparently what staying up waiting for DP to get off work even though I have to work early in the morning is all about! Oh pregnancy! 
Oh and holidaymama, thank you for your list of amounts! That is something I need to start thinking about as well.
