It's not too hard to unroot and then reroot, but I'd rather have a better understanding of what each step actually does
Well, flashing with the above command will replace all of your OS (even the root parts), so you lose root at that point...but yes, the bootloader and radios are untouched by the above component being flashed (that's the OS part (boot/recovery/system images)).

Your bootloader will remain unlocked (its only affected by the fastboot oem lock and fastboot oem unlock commands).

You should be able to just use the above command to return to stock as long as the radios and the bootloaders haven't changed. That being said, whenever Google publishes a new OTA and the accompanying stock image package, you'll want to keep everything (radios, bootloader, OS (boot/recovery/system images)) in-sync.
