Any insight would be apreciated. Thanks.
If you have a DE, you can unlock the bootloader (without voiding warranty) at any time, and install a custom recovery to root.
As far as upgrade path, it depends on if you are stock, or how close to stock if you have modified it. If stock, just take the OTA's, one at a time, to keep your settings, data, apps.
The OTA Update files have a manifest in them containing a list of files, and check sums for those files, which it needs on your phone. If files it wants to be there are missing from your phone or do not match the check sum in the manifest, the OTA will fail (which is why I say depends on if you are stock). If you've removed or replaced any files, you'll need to put them back. You'll also need stock recovery for any OTA to install.
An "easy" way to update is to download the SBF file for the version you want on your phone from -> http://sbf.droid-developers.org/phone.php?device=0
unzip it. Edit the XML file and, if it exists, remove the line for erase partition userdata. Then flash using RSDLite.
With the unlocked bootloader, you can then flash TWRP, CWM or other custom recovery and install SuperSU to root if needed.
