Hmmm, MANY people have complained about the Droids camera. The images I have seen are grainy (ISO too high) and blurry (shutter speed to long). Hopefully Motorola will do a firmware update in the future to lessen this obvious flaw in the Droid's camera.
Also, do a search for facebook in the app store. There are a few 3rd party Facebook there. Maybe one does better at picture taking and transfer than the native app.
