Google News tips, tricks?

Since my Twitter question got such a response, I have another open query. Has anyone come across a good guide to Google News optimization? My site does very well in the web results category, but we get creamed in news, despite our standing as the #1 local site in the market. I’m set up on site maps, and I’ve tried to optimize, but I’m frustrated by the lack of good actionable info online (what little there is seems to be targeted at poser news sites). Anyone have good ideas?
