There's a long thread on 4.2.2 already.

Re: 4.2.2 update
What about the bootloader? Will it relock it? Or is it left alone?

Re: 4.2.2 update
Also, I was just reading through that thread and it said if you have SuperSU that it won't unroot. Is that true? Or do I need to use ota rootkeeper? I know that thread may have the answers I'm looking for, but I'm too tired to read through it all. I ask all these questions because I have no computer to reroot and reunlock the bootloader with.

I was on JOP40D (4.2.1) Stock, rooted, with CWM 6.0.2.3. I downloaded this OTA file http://android.clients.google.com/pa...D.6ece895e.zip from the link in the other 4.2.2 thread (http://forum.xda-developers.com/show....php?t=2144330)

I booted into CWM, and flashed the downloaded ZIP file as normal
When I told CWM to reboot, CWM warned me the update would flash stock Recovery and do I want to STOP this from happening and I said YES.
It then said I had lost root, and do I want to restore root, and I said YES.
It then booted into Android and continued with the upgrade.

I now have 4.2.2 stock installed (JDQ39), and still have root and custom recovery, and an unlocked bootloader.

From what I have read, if you 'sideload' the update using ADB, or do a normal OTA update, you will lose root and custom recovery. However, using the steps above will keep root and recovery for you

TWRP is same to CMW, but for sure you should install Voodoo OTA Rootkeeper, backup SU then flash the 4.2.2 update.zip. Finally, open Voodoo and restore the backup SU --> your Root is kept. Just in case you need to verify root will work or not. Go to Play Store, install Root Checker (joeykrim) and check your root permisson.

I updated my N7 to 4.2.2 without removing root by these steps above.
