And some additional info:

1)Not formal true 'cause WWII is official name of war lasted since 01.09.1939 (german invasion in Poland) to 02.09.1945 (Capitulation of Japan) So neither civil was in China nor Winter War are counted as parts of WWII.
Sofar, there were US sailors killed in the fall of 1941 by German U-Boats, while escorting UK-bound convoys to mid Atlantic. The German sank one US destroyer and heavily damaged another, both with large loss of life. Roosevelt did not seek a declaration of war from Congress over these incidents, possibly because he was on pretty thin ice as regards the Neutrality Act. The first official American casualties were at Pearl Harbor.

The first Germans killed would have been in their invasion of Poland, in September 1939.

Lesley McNair was one of two three-star Lt Gens killed in the war, and he was killed in July 1944 by bombs dropped short by the US Army Air Force (it had changed from the Army Air Corps in 1940). The other was Lt Gen Simon Bolivar Buckner, Jr., killed in the Okinawa operation in the Pacific. Buckner's father had been a Confederate general, who surrendered Fort Donelson to U. S. Grant in 1862, when Grant got his "Unconditional Surrender" nickname. He probably thought these were uncharitable terms from his old friend Sam Grant. It was the first time they had seen one another since Grant had resigned from the prewar army under a cloud, due to his heavy drinking. Buckner Sr had loaned Grant the money to travel back east from their duty station in California. Its not recorded whether Grant ever repaid the loan.

2) is true. His name was Calvin Graham. There is an article about him at Wiki: http://en.wikipedia.org/wiki/Calvin_Graham . He had kinda interesting biography.

5) Generally speaking pilots divided on two categories: shooters and targets ;)
There are a lot of high-scored aces that were killed in action and even more pilots with 1-2 victories that survive the war. It's all about the mathmatics: the more aircrafts has the country the less score has its pilots and vice versa.
