We expand upon our previous Monte-Carlo-type study of 3-family mass matrices which lead to the experimentally-determined KM matrix and satisfy the constraints imposed by B{sub d}--{bar B}{sub d} mixing, {vert bar}V{sub ub}/V{sub cb}{vert bar}, B{sub K} and CP violation. Scatter distributions in {vert bar}V{sub ub}V{sub cb}{vert bar}, {epsilon}{prime}/{epsilon} and x{sub s} vs m{sub t} are presented for the standard minimal Higgs structure as well as top quark mass histograms for the minimal and 2-doublet Higgs models. A top quark mass in the range of 100--200 GeV is strongly favored with all the constraints imposed, but if the lower bound on the CP-violating J-value is completely relaxed, a secondary probability peaking occurs in the mass histograms which lies above 220 GeV in the minimal Higgs model. 19 refs., 5 figs.
