Lots of good ideas in this thread.

One note on the radio you've added - if it has presets, maybe you can set them all to news stations. In the '03 blackout, 1010 WINS was off the air once the power went out - but WNYC (public radio) was still working, because they'd installed a generator after 9/11. They were able to put out the word as the story unfolded, with useful information - that the power outage was widespread and not going to be fixed soon. That let me tell several laggers who were hanging around on the subway platform that there was not going to be a next train - and we were able to get out through the pitch-black stairwell in a group with a couple flashlights.

If there are no presets on the radio, perhaps another laminated card with as complete a listing as you can find of likely alternate news sources - many kinds of emergencies will be putting stations off the air. Also, consider stations that are locally run - the Clear Channel and other mega-networks are less likely to have locally relevant information.
