My vote in no particular order: Jon Corzine, Hillary Clinton, Ted Kennedy and Robert Byrd
I essentially agree with your analysis with the following caveats.
Santorum is very vulnerable in PA with Rendell also up for re-election... perhaps our most endangered Republican. This seat must be saved.
Top RATS to target: Dayton, Stabenow, Nelson of FL, and I would move Cantwell up, as well.
Destroy Jim Jeffords for his treachery.
We may have a freshman D in NJ if Corzine runs for governor in 2005 -- essentially an open seat.
