Looking for help researching Grandfather

My grandfather was Staff Sergeant John F. Tawrosza, he was in the 553rd AAF Base Unit, 386th BG, 9th AAF. He enlisted on December 7, 1942 and was in the Battle of the Bulge. If there is ANYBODY who can give me any information on him or anyone he worked or flew with, I would really appreciate it. I'm also looking for pictures and flight information if that's at all possible.
Thanks in advance for any information that you may be able to provide.
