Download the 4.2 image from Google and install it manually (as if it were a custom ROM). The easiest way to install it is using one of the toolkits, such as WUGs.

Hi Nocturnal

I've moved your thread to the International GSM Galaxy Nexus All Things Root forums where people can better assist you. I'm sending you a PM also, so let me know if you have any problems with this move.

Thanks for your patience.

Ok sounds pretty straight foward. So after i have 4.2 installed do i just root? And i have CWM already installed will that need to be reinstalled after i install 4.2? Or is there a whats the best steps to do it? Thanks for the help!

Fast boot to unlock, push a recovery, and then flash the superuser files

Or use one of the many toolkits

So if i install 4.2 with the Gnex 9.1 toolkit can i root it even though it doesnt support 4.2 yet?

There's no option to root 4.2 yet on Mskips root toolkit, unless you donate (donations get you updates before everyone else). However, if you can hang on for a bit (I'm unsure when) the public update to support 4.2 will be out.

Best bet is to keep an eye out here.

There is another option; you can flash a fully rooted stock ROM, based on JOP40C image that also has Busybox and is odexed and is available from XDA developers here http://forum.xda-developers.com/showthread.php?t=1737849. I have flashed it myself and it worked flawlessly.
What you need is the latest TWRP custom recovery (2.3.2.0) which is now set to handle the multi-user issue (Google introduced this with 4.2), which basically creates an issue with your backups not being seen by the recovery. If you want more on how-to's and how the partitioning system has changed in 4.2 then I suggest head over to TWRP Android 4.2 Updates, Multi-User, and TWRP | TeamWin which explains it all in more detail.
By-the-way, I understand that CWM recoveries haven't yet dealt with this problem.
