I'm afraid I really don't understand what you did, nor what the situation is now. When you say you did a Spotlight search and "it shows the old desktop icon" what does that mean? There is just a Desktop icon which is applied to the folder Desktop that is in your home folder. If you type this into Spotlight:
Desktop kind:folder
Do you see the Desktop icon? If you hold down the Command key and click on it, what happens?
If you open a program you were using that has one of the items that you had on your Desktop, and you go to Recent Items and select the file, does the file open?
Have you looked in your Trash? Is anything in there?
Finally, two pieces of advice: keep a current backup of all your own files on another drive (preferably a drive that is big enough to allow you clone your entire startup drive, and that you can boot from), and do not keep a bunch of stuff on your Desktop. Save things to appropriate folders inside your home folder.
Sorry I can't be of more help, but from what you've said I can't imagine exactly what you did, nor what state things are in now.
