Nandroid File Location

Got my Nexus Thursday so rooted and flashed recovery (twrp) Friday and did a nandroid in prep to flash aosp ROM but when I went looking for the file I noticed its in /data/media/tarp/backups as opposed to /sdcard/tarp/backups. Is there a way to change the directory? I created the backups folder under the trwrp on the sdcard but the backup didn't save there where I did a 2nd nandroid as a test. Do I need to fix permissions or anything?

/sdcard is a link to /data/media. They are three same file.
Just make sure you use the latest version in TWRP as it properly handles the changes in directories introduced in 4.2.

Cool. I downloaded the image from the twrp site and installed via adb so it should be correct. I guess I can install Goo Manager and make sure its up to date. I was concerned that if I wipe /data before a restore that I'll delete the nandroid.

Note that in TWRP a factory reset will format /data EXCLUDING /data/media. This means it won't wipe your /sdcard.

What do you mean by reset?
Basically you have 3 options
1- Format data in cwm
This will keep your current rom but wipe all user data - it will be like you have just flashed rom
2- flash different custom rom
in cwm format system data and cache
mount system data and cache
flash rom zip
note some roms require certain kernels to boot
3- Flash stock rom via odin
wipes all data and returns phone to stock ie first time you switched it on
