Can reducing the resolution on say an 8 meg camera to 5 megs reduce the digital noise? Is there more noise at telephoto than at wide angle?

The digital noise is a factor of the quality of the sensor, and the ISO setting.

Reducing resolution results in some pixel averaging, and this tends to cancel noise. If the reduced resolution is OK, you can also do this with editing software.

Terry is correct if we are talking about the raw output from the sensor, but the processed image owes much to the algorithms used to interpolate that raw data, and to convert it to am image file.
