Please help restore DMG missing partition and access file vault.

Question

I am quite emotional at the moment, if anyone can help me access my files, pictures of my baby daughter and important documents.. I would be extremely grateful and willing do make a donation via paypal.
I have a 160 GB hard drive, which was partitioned as 30GB Spare and 130GB with my operating system and user files, including my filevault user directory.
My computer was downloading movies which filled up the 130GB partition, most of the 130GB is contained in my personal filevault user directory, my computer became very slow and unresponsive and i tried to free up space by deleting files which i no longer needed.
The machine became slow and un-responsive and required a number of forceful shut downs and restarts until the machine would no longer boot up, I inserted the OSX CD and attempted to boot from CD and use disc utility which now only displays my 30GB storage space, I was forced to install OSX on the remaining 30GB partition.
Now running OSX on the 30GB partition i used DISK DRILL to scan my hard disk for the missing 130GB partition which it did and i was able to save this as a DMG file to a external hard disk, now i am able to get this DMG to mount in the OSX i am running on the spare 30GB space, however i am not able to access the majority of the data inside the file vaulted user account.
I would like to know, would it be possible to restore the missing partition, as it remains on the HD but seems to be hidden.
Or is there somehow i can login to the user account on the mounted DMG ?
I am not very familiar with using terminal and would be extremely grateful for any advice or support leading to the recovery of my files.

Is there anyway to recover the larger partition ? In disk utility i made the mistake of pressing the - button which has left me with the following: 
[NO NAME] - is currently where i have installed OSX temporarily.
And the grey space which contains my previous operating system and all my information which i desperately need to retrieve.

Probably not.     You've now deleted the partition.  It was probably useless anyway, though.
When i run disk drill or other disk recovery tools i am able to see the partition including including the files and my personal sparsebundle.
But you can't open the sparse bundle, much less see any of the files inside it, right?
Since you've already recovered the (probably-damaged) sparse bundle containing your encrypted home folder, you'll have to work with it.
I'd strongly recommend making another copy of that on another external HD and putting that "on the shelf" before doing anything else to it.   I suspect you have little chance of recovery, but don't take the risk of further damage.  
You haven't answered my earlier questions:
Have you tried to run Repair Disk on either the original or copied partition?
If that doesn't help, this might:  http://www.thexlab.com/faqs/fixfilevault.html
Do you have Time Machine backups?
Obviously, now that the partition has been deleted, you can't run repair disk on it, but try it on the recovered disk image.  
You need more expertise than either Christopher or I have.  Since Apple no longer uses "legacy" File Vault, it will be more difficult for them to help, too.
Is your Mac covered by AppleCare?  If so, give them a call. 
If not, your nearest Apple Store Genius Bar might be able to help:  http://www.apple.com/retail/geniusbar/ 
Or check for an Apple Authorized Service Provider: http://support.apple.com/kb/HT1434?viewlocale=en_US
If not, one of them may know of an outside service than can help.  That will be quite expensive.
