Moving back to stock from Cyanogenmod

Hi all, I just dug up my old S3 and need to go back to stock. It has a CM11 nightly on there with the MK3 baseband and CWM recovery. Needless to say, I've been out of the loop for the past year or so and all of these threads about Odin and the newer updates have my head spinning! I want to go back to stock but also want the ability to re-root and load a different ROM later on. If I use the Odin one click here (http://forum.xda-developers.com/show....php?t=2755793), would this cause any problem with re-rooting, recovery, or whatever else? I was burned on my newer Droid MAXX when I updated to a firmware that couldn't be rooted so I don't want that to happen in this case if possible.

Thanks!
