"Fishrrman, how would this be easier with a CCC backup?"
A CCC (or SD) cloned backup is "nothing more" than a finder-mountable drive, like any other drive.
Everything "is there" in POFF -- plain ol' finder format.
You can copy one file from it.
You can copy several files from it.
You can copy a folder from it.
You can copy a group of folders from it.
You can even "clone the whole thing back" to your internal drive if you need to.
It's "just another drive with stuff on it".
No sparse bundles and you don't "need an app" to access it.
What this means in rebuilding your user folder:
A cloned backup of the original (and now messed up) home folder will make it easy to open, and then "pick and choose" the stuff you want to move into a new, working home folder.
It will be a matter of just "picking up a file here, and putting it back down there".
HOWEVER -- AND THIS IS VERY IMPORTANT:
There are things you must be aware of when moving files like this.
First thing -- to avoid permissions problems...
1. Mount the cloned backup in the finder
2. Click ONE TIME on the drive icon to select it
3. Type "command-i" (eye) to bring up the get info box
4. At the bottom of get info, click the lock and enter your password
5. In "sharing and permissions", put a check into the box "ignore ownership on this volume"
6. Close get info.
Now any file you copy will "come under the ownership" of the NEW account (into which it's being copied).
YOU MUST DO THIS step, or else there will be problems.
Next thing:
You CANNOT copy the "first level of subfolders" within your home folder. These "are more than just folders" (I think they're called symbolic links).
That means, you cannot copy the folders named documents, movies, music, pictures, etc.
HOWEVER...
You CAN copy files and folders that are INSIDE of these folders.
So... if you want to move pictures, the way to do it would be to first open the pictures folder (in the home folder) on the external drive.
Then, select the items inside you wish to move (you can even select things like the Photos library), then, drag and drop them "into" the Pictures folder in your new account.
In a case like this, I would permit the copied file to replace the existing library file.
Some updating may be necessary. For instance, you might have to "redirect" Photos to the new library file.
I would suggest you also KEEP HANDWRITTEN NOTES so you know what's been moved and what remains.
It's a bit of work, but it can be done, and it's probably the only way to clean up a "messed up" home folder.
I recommend that you print out this post and keep it for reference.
