I've added three items to the left column:
- A link to the military casualty count maintained by lunaville.org based on this methodology;
- [Update: Just a link to, see comments for details] A chart of civilian casualties provided by iraqbodycount.org based on this methodology;
- A dollar estimate of the cost of the war to the US from costofwar.com based on this methodology;
I have not personally checked these numbers, but they all look as if they are serious attempts to provide meaningful estimates [and in the case of the military data, a simple tally] of very gloomy data sets.
