The only thing in that list that Vim does not encrypt, if you decide to write an encrypted file, is the viminfo file.

See :help encryption, and also http://vim.wikia.com/wiki/Encryption

Oh, I see. You want to write UNENCRYPTED files, but have Vim's "helper" files related to your editing be encrypted.

I could see the utility of this. But then Vim would need to ask for a password every time it started up and read the .viminfo file.

I think it might be easier to set up an encrypted home directory, and set your backupdir, directory, and undodir to reside within. Then Vim doesn't need to worry about it at all.
