I messed up my mac...Halp.

Question

So. I tried to change my home folder name on my mac. A tutorial told me to create a new admin account then use terminal and type
'sudo ... ... ... 'oldshortname' 'newusername''
Something like that.
I then had 2 admin user acc's that looked completely new and all my settings lost e.g. wallpapers, login options etc etc.
The original user file was in some sub folders and I had to verify each folder with my old user acc details but all my custome boot settings lost. 
After all this confusion I decided to create 1 admin acc and try to just get all my settings restored.
Below is a screenshot of the current files;

I want to restore my mac using 'MacBook' as the time machine file and the blue highlighted 'jonathanbartlett' user file as the main user under the 'users' folder.
If you can shed anylight on this please help.

Well, I think you may be able to move your 'JohnathanBartlett" folder into your "Users" folder, create an admin user with that name and hopefully be okay.
If you're playing around in the Terminal with Sudo and taking screen shots, you're probably an Advanced User (or on your way to becoming one).  For the sake of anyone who reads this post who is new to Macs, let me explain my answer...
First, I would take a look in that "JohnathanBartlett" folder and see if the contents of the folder match what you have on your computer.  If so, I would copy and paste it to your desktop (for backup).
Then I would open System Preferences (in the Apple Menu, top left of the screen) and go to Accounts.  To make changes, you may need to click the lock icon and type in your password.  If there is a "JohnathanBartlett" user on the computer, delete him by choosing that user name, and clicking the "minus (-)" icon..  In the popup window, tick the option to delete the home folder.
Paste the "JohnathanBartlett" folder back into the "Users" folder, and add that user back to your computer by clicking the "plus (+)" icon.  When you choose the Account Name, you can use "Johnathan Bartlett" with a space.  The short name is what's important.  Make sure it stays "johnathanbartlett."  When you click "OK" a screen will pop up that acknowledges there's already a home folder with that name, and asks if you would like to use it.  Say yes and your problems should be solved.  If all went well, you should be able to log out as the current user, and log in as "johnathanbartlett."
Before you close System Preferences, make sure you tick the box that says, "Allow User to Administer this Computer." 
I like to keep at least two accounts on all of the computers I administer, one for the main user and one for an Zadmin.  (I chose Zadmin because it comes up last on the list of users.)  Even if the primary user is admin, I like to have a second Admin user (even on my home computer).  Sometimes our girls have problems that only affect one user.  It's handy to have another Admin account you can log into and fix specific user problems.
That doesn't really have anything to do with your problem, it's just a side note opinion piece.
Let me know how your home folder works out!
