Those posts are specifically targetted at those intending to use iBooks as that is what thE books support in iTunes integrates with.
If you are using Stanza, then the eaiest way to get books into Stanza is using the Calibre Content server as described
here in the Calibre User Guide, and do WiFi based transfers. There is no automated support for transferring books to Stanza via USB and iTunes, although it can be done manually for systems running iOS4 or later.
