We present preliminary measurements of branching ratios and CP
asymmetries in 5 charmless decay modes of the B mesons and precise
measurement of direct CP asymmetry in Cabibbo-suppressed charm decays.  We
used 180 pb-1 of the hadronic-b data stream at CDF at Tevatron Run II.  The
decay mode B_s --> phi phi has been observed for the first time, with a
branching fraction of (1.4 +/- 0.6 +/- 0.2 +/- 0.5) x 10-5.  We also
present the first measurement of the branching fraction B(B_s --> K+ K-) =
(3.56 +/- 0.57 +/- 0.50 +/- 0.43) x 10-5.
