In the section "To boot your desktop model ReadyNAS from USB:"
first it says hold the Backup button. Then for 2-bay models it says to hold the Reset
button. Must be an error because the Reset button takes you to the boot menu.

Agreed.  I think it is intending to tell you to hold the backup button for 30 seconds instead of 15.  Though if you have a USB drive that has an activity light, that will tell you when the NAS begins booting from USB.

Extra Credit Question:  On the back panel is a small sticker near the Ethernet port.  It covers a 4-pin header.

What is it for?

If you have a suitable adapter, you can connect the header to a serial port on the PC, which will give you console access w/o needing ethernet.
