Keith,
My Taranis is on 2.1.9 so I don't know why you would need 2.2. Turn on your radio, hold the "menu" key (should say "Radio Setup" on the top of the screen), short press the "Page" key 4 times, it should show "5/9" in the upper right corner of the screen. That screen has the Open TX version info. If it shows:
FW: opentx-taranis-plusw
VERS: 2.1.9
DATE: 2016-09-15
You should be good to go. You shouldn't have to do anything to the radio unless you want custom sounds or some other custom stuff.

(Make sure you hit "Exit" before powering the radio off.)
