We present measurements of branching fractions and CP-violating asymmetries for two-body neutral (B) over bar meson decays to charged pions and kaons based on a sample of about 88x10(6) Y(4S)-->B (B) over bar decays. From a time-independent fit we measure the charge-averaged branching fractions B(B-0-->pi(+)pi(-))=(4.7+/-0.6+/-0.2)x10(-6), B(B-0-->K(+)pi(-))=(17.9+/-0.9+/-0.7)x10(-6), and the direct CP-violating charge asymmetry A(Kpi)=-0.102+/-0.050+/-0.016 [-0.188,-0.016], where the ranges in square brackets indicate the 90% confidence intervals. From a time-dependent fit we measure the B-0-->pi(+)pi(-) CP-violating parameters S-pipi=0.02+/-0.34+/-0.05 [-0.54,+0.58] and C-pipi=-0.30+/-0.25+/-0.04 [-0.72,+0.12].
