I'm sorry, but this reply is providing more problems than solutions. Hopefully someone more knowledgeable on the state if BIP32 software will come along and help...
Re bip32.org: I'm not familiar with them, but I took a quick look. They are producing BIP32 brain wallets, which is something you really don't want.
Re terminology / printouts: you'll want to save your "master extended public key" on one sheet, and your "master extended private key" on the other. Because the master extended public key can be derived from the master extended private key, you don't need to have both on the private sheet. It's up to you if you want to encrypt your master extended private key, but if you do, you should make sure it's encrypted using the BIP38 standard (simply because it's a standard likely to be supported by many wallets).
Although you shouldn't use bip32.org to create them, just for the sake of completeness: your master extended private key is next to the label "BIP32 Extended Key", and your master extended public key can be found by choosing "Info: m" next to "Derivation Path", and then looking next to "Derived Public Key"
Unfortunately, there's a lot I can't answer, e.g.:
- Easy and secure way to generate a BIP32 paper wallet (and not a brain wallet)
- BIP32 mobile app that's not in beta (there are several that are still in beta testing)
- BIP32 mobile app that supports a watching-only wallet
If you have an iPhone, you might want to look at breadwallet. I don't know anything about it, but I do see that it's apparently not in beta, and it supports BIP32. I don't know if it supports watching-only wallets.
Good luck....
