[AT&T LG Optimus G] [r.]GimP:
yes that sounds fine, in that case I would just make the apps and messages backups with titanium/backup your mobile

I'm not 100% if the lgnpst flash to JB wipes user data or not, but after that you can flash pretty much ANY rom for our device, then just download titanium/backup your mobile from the app store and point it to the directories on the sd card, and restore selectively.

For the most part you can move everything from /sdcard to /external_sd and move it back over when you're done, I think the JB radio (or modem, both terms apply) works very well for everything I've used (and yes they play a significant part in wifi and gps also), and I was a pretty hardcore flash-a-holic for a really good while, still haven't tried the hybrid modems and people rave about how well they work. Sounds like a good plan you got going, once you're up with the partitions and the JB modem from 4.1.2 you really should have no issues, and once you have that freedom, and she will as well to try out all manner of ROM's, you'll find you get really good at backup/restore out of necessity. Happy flashing.

If you need any specifics, aside from the step by steps of the other threads I'm glad to lend advice, just let me know

-edit- you can make multiple backups with each program by the way, titanium and backup your mobile.

Titanium free says only one backup per app, but in reality just hit the batch button on the top right, looks like a check mark, have it get all apps and system settings, then just move the whole folder you set for titanium off of the device for safe keeping. This way you can backup everything running right now, then if you want to restore the other one, you could even do it again, if you just wanted to cherry pick some stuff, then flash, etc. Titanium free wont let you make multiple copies of the same app, but it also WONT delete extras if you already have them, so if you dump a few titanium folders into eachother and merge them, you can then choose any of the backup files or data or both from each date.

The reason I use both programs is as I said earlier, backup your mobile handles SMS/MMS very efficiently, and occasionally I'll let it grab a few user apps, and system apps, because when it restores them, it restores for example, flash player from LG stock rom, as a user app, and it continues to work flawlessly. Titanium can't get over it being a system app, and sucks at restoring flash.

However, titanium is GREAT for also saving user data, not just the program itself. ie.. savegame states for any app you have that doesnt explicitly sync online, or the login data for facebook, or adfree with the most current hosts so you dont have to redownload or even type your logins, very convenient.

My personal order of operations before I flash a new rom, or even upgrade to a new version with a clean flash instead of a "dirty" is to fully backup all apps/system data with titanium, then hit ByM for contacts/sms/mms/bookmarks/user dictionary/apps

then a nandroid backup, since it is basically a perfect snapshot itself, just like turning the phone off, and back on.

after rom flash / gapps, I boot, setup google real quick, goto app store and cancel the 5 million downloads, except for titanium/ByM

after those download I roll my messages/user dictionary/contacts/ selective apps I know i'll use, and the same with a few from titanium.

This way I'm less bloated with crap I probably don't use everyday, and if i need it, its a few taps away. It's a very painless process and a lot of peace of mind having everything safe, and allows you to try alot of unstable crap knowing how easy you can always roll your CWM/TWRP backup over to the device like you never left.

Sorry, I'm a fan of ranting. Pics for adb driver steps explained in previous post, and the backup part, for reference if you ever need them.
