Welcome to the forums.
I think you're slightly confused on the OS upgrade process. If it shows 18.104.22.168, then that's what's installed on your phone. As for the HTML email, you will have to resend your service books. To do so, log into your BIS account online and click the link to send service books.
Also, by default Docs to Go is not checked to install with the OS upgrade. To get Docs to Go on your device, connect your device to Desktop Manager and select the App Loader application. Scroll to Docs to Go and put a check mark in the box, follow the steps and it will install on your device.
Also, for future reference, the wipe handheld option in security options will only wipe the data off the device. If you want to wipe the OS off of the device, you will need JL_Cmder. Check BlackBerry FAQ - BlackBerryFAQ
for more info.
