If I removed the userdata.img from image-mantaray-jdq39.zip could I just flash the zip in recovery?
No, images have to be flashed via fastboot. Just reboot into your bootloader, extract all the .img files to a folder, then go to a command prompt with your N10 plugged into USB and do:
fastboot flash system system.img
fastboot flash boot boot.img
That'll get you on 4.2.2 stock. At that point, you can re-root using whatever method you choose. Your bootloader will still be unlocked, your data will still be intact, etc.
