Woo! CollegeBoxes found the duffel. Contents: A bunch of DVDs (yes, mom, including PotC and X2), sweaters, my lamps, a surge strip, my infamous sheep pajamas, and more! And the guy I talked to was really helpful, and he believes that they are indeed liable for stuff they break, so three cheers! Hopefully they'll be able to find my remaining items now they have a better idea of what they're looking for.
