I've got my HP2550L Color Laserjet set to '75-105gsm gloss card' - the
paper goes through slowly, prints hot, and spits out with impeccable
reproduction.

Yes - a very good idea indeed. I felt the pain of soaking/scrubbing on
Saturday, when I did a batch of 24 boards (as 2 lots of 4x3 12-up). It's
a task with as much enjoyment as scrubbing a filthy toilet bowl with a
worn toothbrush. To make matters worse, I tried the dishwasher soaking
with the second batch, it came out so bad that I had to scrub the board
clean and start again. So your label backing paper idea came as a
God-send, only 24 hours late :P

Irons and me don't get along very well. My trusty second-hand $35
laminator has lifted me out of the harsher levels of hell.
I think my final setup will be:
∗ artwork with slightly thinner traces
∗ label backing paper, printed slow/hot through printer
∗ 2 or 3 passes through laminator at slowest/hottest setting,
with paper+board enclosed in a folded strip of thin card
I'm out of blank PCB - will buy some more today, try it out and report
on results.
Cheers
