Any good reason for keeping the male around? If it releases it's pollen, the pollen can and likely will find your ladies. Pollen is a fine, light particle that will float all around the house on clothes, hair, a/c currents...this results in unwanted seeds and much smaller yields. If you are not ok with seeds, place a plastic bag over it, chop it, tie it up, and dispose of it without remorse.

Ditch the clock radio. The light will screw with the ladies, and the plants have no ears. <sigh>

Depends on the strain, but 8-12 weeks flowering for an indica dominate, 10-14 weeks for a sativa dominate. Of course this is also determined by the lighting, nutrients, growers experience...
