HELP: Can login but desktop stalled


After I force quit my powerbook(G4 1.25) and restart, I can login and have the old background image. But the top menu only show spotlight without anything else include my desktop folders and dock. I have turned FileVault on and I can't resore my desktop file. I tried all my best include using Data Rescue X but still can't get my desktop back. I have two partitions. Can anyone help me in here? Many thanks in advanced.
