I plan to jailbreak a used PW2, FW 5.7.4. I am following the following instructions to prepare:
Software Jailbreak for PW2, PW3, PW3W, KT2, KV, KOA and KT3

Make Ready:
Consider the following bullet list a "Step #0" that can be done in any order.
For some firmware versions, your Kindle must be registered with Amazon to access the required menus.
The general rule to cover all versions, is: If not yet registered, do that now.
Read the rest of this specific section before connecting to the Internet.
Some of the more recent firmware versions are very aggressive about doing an OTA (Over The Air) update.
Which will currently update to a version that can not be jail broken.
Currently the best way to avoid OTA updates is to add the OTA blocker directory (folder) name to the top level of visible USB storage.
The blocker directory is named: update.bin.tmp.partial
Use that exact name, no additional extension, no contents.

As I understand it, the first thing I must do is
add the folder update.bin.tmp.partial to the root folder of the PW2 when plugged into my PC via USB. That seems very simple. After that I can safely connect to wifi to register without danger of the PW2 updating its FW. Is that correct?
