I found a site with somewhat accurate numbers relating coalition casualties in Iraq, including the wounded.
You can find it
HERE
Acording to it, there have been 777 coalition deads, amongst wich 674 of them are americans.
It reports also 3466 coalition wounded in battle, from wich 3022 of them are american.
The site seems to have links to the DOD (Department of Defence), and seems quite complete, including news snipets and other relevant material.
