Me and my hometown

This is me and my first photo shoot around town at night with my newly acquired D1H (and my new hat...)
I tested it by night because there was a beautiful moonlight and I love the surreal and out of time atmosphere given by the artificial urban lighting, it becomes like a readymade life studio.
Anyhow, I am new to photography and need some technical advices. ONE question is: how do I eliminate lights glowing like a big ball?? I get the same from the moon, can't get a clear image, my guess would be that I use a flash? This photo was taken with a 1600 ISO exposure.
Thank you for your comments and help.
