I have not rooted my Nexus 7 yet, I will soon, I'm kinda waiting for the warranty to end. But I have been reading up on it and how to do it, etc. XDA has a couple of threads where some complain that the update 4.2.2 caused problems for their rooted Nexus 7. Then there are others that report no problem at all. Who knows? I'll try to find the threads and post them here.

I seriously suggest once you have it rooted to looking into Titanium Backup, with it you can do a back up of apps and data before a rom change or firmware update and then restore it afterward.

Since I updated to Jelly Bean 4.2.2 on my Nexus 7, it acts like it is not rooted. Any ideas??
If you're not you should be running something like "Voodoo OTA Rootkeep" or "Android Root Toolkit" (there are probably others). Both are availible in the play store.
These programs protect your Root access by saving it to a file. It is not uncommon for a OS update to remove the Root access status from your device. (4.2.2 removed the Root access from both my Nexus 7 tablet and Galaxy Nexus phone.)
These utilities allow you restore the Root access with a one click instant restore. Always protect your Root! If you don't have a protected Root you will have to re-root and then install a root protector. You should be good in the future.

Try either Google Nexus 7 Toolkit or the Wug Nexus Root Toolkit. If you use Wug's you'll have to follow the directions at the bottom for the work around for 4.2.2. Hopefully one of these will bring you unit back from it's coma. I have used both of these programs to fix mine when I thought it was bricked (but not with 4.2.2). Wug's has a nice advanced utilities section.

Now that you are back up, rooted and running I would give some thought to installing Android Root Toolkit (playstore). It will allow you to save and restore your root and some other things. But best of all it will flash a custom recovery.
It gives you a couple of choice of popular recoveries to flash. I use TWRP 22.214.171.124. The beauty of the TWRP recovery is once you boot into it, it has a touch screen GUI and it will allow you back-up and restore directly to flash drive or the Nexus internal storage, no PC is needed. It will restore and backup all your files and the OS in one shot. I have backup copies of all the versions of OS and software I've installed on my Tablet.
I had to send my Galaxy Nexus phone back to Samsung for a warranty repair for a hardware issue. I used TWRP to back it up and restore a factory image. When Samsung received the phone it was completely clean like a virgin phone from the factory. No warranty issues because there was no trace that it had been rooted or messed with. When it came back a simple root, install of the Android Android Root Toolkit, flash of TWRP and a restore. All my files, contacts wifi settings everything. I didn't need to connect to the Play Store to reload anything!

I have thought about rooting my Nexus 7 but I have so far hesitated to do so with regards to the warranty. Can TWRP revert to factory settings without a trace? I can root and if a warranty problems pops up I can set it back to factory settings?
I have a Kindle Keyboard that I jailbroke (word?) with screensaver and custom fonts so I do have some idea about rooting and JBing hardware. Thanks for your time.

To relock the bootloader I use the OEM Lock option in Wug's Nexus Root ToolKit (which is a PC Program). Wug's will also download a stock factory image for you if you need one, so you could also use Wug's to reflash and relock.
I personally like to restore images from a backup that I have made within TWRP and then only use Wug's Toolkit to relock the device. I think that helps avoid issues like Carol ran into. all the other time I just leave the bootloader unlocked for convenience.
So once a factory ROM is restored and the Bootloader is locked there are no issues with the factory warranty. In my case my Nexus phone went back to the factory twice under warranty after being rooted and custom ROMs loaded. Once restored and relocked Samsung honored the warranty with no problem. Actually on the second warranty return they replaced the phone. They even paid for shipping both ways, both times.

What did you use to restore it? Was the tablet restored from a file that was actually on the device or from a file on a external device. Sounds like there is some old data there. Go to settings > internal storage. That will tell you what is using up all the sace.
I would tell you boot to recovery and wipe both the cache and the Dalvik cache but I don't know what recovery ROM you have

I have the stock Google JB 4.2.1 on my computer as a backup just in case.

Based on what you said I would flash the stock Google 4.2.1 image. I don't like that you had to flash those 4 files separately.

Snorkler, yesterday I tried booting into recovery mode and all I got was a little android with a red exclamation mark on it. So I'm thinking I need to flash CWM onto the tablet using the nexus toolkit. Is that right?

You need to (quoted from the link):
extract the stock image and pull recovery, userdata, boot, system
fastboot flash each of them
boot into stock recovery and u will get stuck at the laying android
push volume up + power til it enters stock recovery
do factory reset and u should be good to go.
reflash custom recovery, and reflash custom rom (if applicable).
But try a factory data reset first. I'd try the fastboot erase userdata command, too, before doing what I posted above.
