OS X :: Desktop Files And Bookmarks Gone After Reset Admin Password

I have a Powerbook G4 running Tiger. I forgot my admin password (which was the only user account I had), but I couldn't find my install disc. I have since found it, but since I am the impatient type, I went searching google to figure out how to reset my password without the disc. One website told me to change the name of my "home folder," so I changed it from "Jason" to "Hello." It then said to reboot and type the following at the command prompt: "sh /etc/rc"

Which I did, and a bunch of text came up. Then I typed: "passwd Jason" to change the admin password. It prompted me to enter a new password twice, which I did. Then I rebooted. When the login came up, it had two logins to choose from, "Jason" and "Other." I chose Jason and entered my new password. When it logged in, all my desktop files were gone and all my Safari and Firefox bookmarks were gone. In my "/Users" folder, it now has "Jason" as the home icon, and beside that there is a folder called "Hello." In "Hello/Desktop," I found all my files that used to be on my Desktop. How do I get my old account back (Hello)? I still don't remember the password. Do I need to use the disc? Should I just drag all the files from the "Hello/Desktop" folder to my "new" desktop?

Also, when I went into terminal, and typed "ls -a /Users" it came back with this:
..DS_Store Shared Hello
...localized Jason
