We present the updated analysis of Bd, Bs , and Lambda_b decays into charmless two-body final states using 6/fb of data collected by the CDF experiment. We report the first evidence for the pure-annihilation decay Bs->pi^+pi^- and improved limits on the Bd->K+K- branching ratio. We also report the first measurement of branching fractions and CP-violating asymmetries of doubly-Cabibbo suppressed B+ --> D0 K decays in hadron collisions, using the approach proposed by Atwood, Dunietz, and Soni (ADS) to infer information on the CKM angle gamma in 7.0 fb-1 of data. The relevant parameters are determined with accuracy competitive with best B factory measurements.
