Nadda.  I tried my emergency boot floppy, but the floppy drive doesn't even spin up.

Time to open her up and look at her. Take photos to post here. But no doubt it will need a recapping.

Are the 180 screens the same?  I recently acquired a 180 that is in amazing condition and works perfectly (with some slight tunneling on the screen after an hour/hour and a half or so).  Is there some kind of preventative maintenance I should be doing on this guy?

They are not the same. The tunneling means that there is a leak along the seam of the glass plates - it's unrepairable. You need a whole new LCD in that machine. the PB 180 has an Active Matrix Screen, the PB 160 I believe is passive. Passive displays do not tunnel and would have a different connector and video driver board in the machine compared to the 180 and its active matrix screen.

You can upgrade however, using a 185c screen to get a color PowerBook with a screen swap. Nothing else is needed.

For LCD Recapping, ask Ferrix97 or Uniserver for detailed information. Ferrix97 did a couple posts on the subject here and a video on youtube for the PB145. The principal in doing to other screens are basically the same:
