For crappies and gills, I always start at the first drop off located adjacent to the largest weedbed in the lake. I fish both shallow and deep along the drop, taking care to fish any vegetation for the chance that there is still shallow gills in there (you'd be surprised how many big bluegills hang in 2 feet of water right now) and then concentrating off the break for suspended crappies. This area for me would be area "3" I would also concentrate on the "corners" of the drop off, as mid-winter fish tend to school and suspend in these areas.
