As Shane has said, DVCPRO HD is not the correct setting for your camera. Your camera does not shoot in that format, you must set FCP to the correct settings, so that it sees the camera source it expects.
Since you have been changing setups with the camera connected, and trying to work with the incorrect setup, my suspicion is that you have corrupted your preferences. The following is what I would do:
Close FCP, and disconnect the camera and turn the camera off.
Go the site-
http://www.digitalrebellion.com/prefman/
and download Preference Manager (free) and use Preference Manager to delete your FCP preferences. Preference manager will allow you to archive your existing FCP preferences if you want.
Shut down your computer completely.
Turn on your camera. Using the menus on your camera, make sure iLink convert is set to off. See page 59 of your manual.
Now rewind your tape in the camera, and once rewound, turn the camera off, plug the iLink (firewire) cable into both the camera and the computer, and turn the camera on to the tape play mode.
Start up the computer.
When the computer is up and running, launch FCP.
Go the the menu Final Cut Pro > Easy Setup and once the panel opens choose HDV 1080i60,
Click Setup.
Now, in FCP, go to the menu File > Log and Capture and see if you have it working now.
