Odexed means that system files and apps are split into two pieces and kept in different places on the phone. This is done to speed things up a bit.
Should I be concerned about slowing down my stock odexed JB ROM, if I flash a de-odexed version of it? The above statement took me by surprise because I thought one of the main advantages of flashing a new ROM was to speed it up. I saw that quote in the "odexed vs de-odexed" definition in the OP.
It's not a very noticeable difference, I wouldn't worry about it. Just be aware of it for theming purposes.

One more question.
Make sure that you use the version of the mod that is for your software version number (UCLEM or UCLG1 see beginning of rooting guide to figure out which one you are on).
Mine says UCDLK3. Am I in the wrong thread or something?
Thanks for the great post!
I do have a few n00b questions:
1. I rooted my gs3 and flashed another rom before doing a backup. Am I screwed if something goes wrong? Would going back to stock and doing a backup help (if there is something to worry about)?
You are not screwed. you can always go back through Odin. I would suggest making a backup before flashing your next rom though just in case.
2. Are there more advantages to using TiB or Carbon to backup apps (& app data) compared to re-installing apps from the Play store?
The advantage is it's faster to restore multiple apps at once, also titanium backup saves app data so things like game progress, login info, etc are restored too.
3. Why do some roms have gapps? Couldn't I just download them from the Play store?
Some roms like CM are not allowed to include gapps so you have to flash them separately. The play store is a gapp so you won't be able to use it to download if it's not there.
Thank you! I had thought as much with the gapps.
Just to continue the learning on my part: I don't think I'm backing up or wiping correctly. It seems that I'm getting nested files in /data (some of them start with 0) The same file structure is nested a few times. Does this mean I did a dirty flash or is this normal? (I did clean it up and copy back onto SD from computer, probably the stupidest way to do it...)
As for a backup, from what I've read it seems that CWM does (or can do) the ROM backup while TB handles the apps right? TB can also do the ROM?
I'm guessing that wiping (when flashing a new ROM) doesn't erase any backups stored on the SD (or can that accidentally be erased too?)
I think that once I fully understand the backing up process, I'll be much better off. (I've been reinstalling apps myself after flashing through the play store...eh, I know its stupid)
