We present measurements of branching fractions and CP asymmetries of several B- -> D(*)0 K(*)- decays, with the D(*)0 decaying to CP-even, CP-odd, and flavor eigenstates, that can constrain the CP angle gamma as well as the amplitude ratio rb=A(B -> u)/A(B -> c), using methods proposed by Gronau, London and Wyler or Atwood, Dunietz and Sony. We use data collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider at SLAC.
