Crampons are probably not required unless you're doing something that's near vertical. Snowshoes could be useful if you're down low or on anything except south-facing slopes. I climbed Flaketop Peak (4510) southeast of Flattop Mountain on Monday evening after work. We had four seasons of weather in that outing - snow, sleet, graupel, fog, sunshine, calm, and breeze.
Given that you're getting off mid-day, you'll probably want to devote yourself to some south-facing slopes. Rainbow, Eklutna, Magnificent, Flaketop, Ptarmigan, South Suicide, McHugh, Bird Ridge Point, Tit, POW/MIA, Pepper, and The Wedge are probably your best chances for success in the Anchorage area. Some of these will requires snowshoes for the approach (Wedge). Others with well-traveled trails or southern exposures will not (Rainbow, Flaketop, Bird Ridge Point).
