I agree with Mike it is a hot image.
One way to reducer the noise is to use the blur tool in Photoshop if you have it.
Simply select the blur tool and then rub it on the noisy areas. You can adjust for how hard or soft the effect will be.
Another way is to lasoo the noisy areas using the control key to add new lasooed areas. Feather it 10 - 20 pixels and then use the gaussian blur filter to smooth it out to your taste.
You can refine this a bit by selecting the red, blue and green channels individually one at a time and rub the blur tool on those channels noisy areas. Often it is one colour channel that is noisier than the others so this way you don't blur the other channels where the data is OK.
Some people use Noise Ninja but i have never used it.
