AB We present branching fraction measurements for the decays B-0 -> rho K-0*(0), B-0 -> f(0)K*(0), and B-0 -> rho K-*(+), where K* is an S-wave (K pi)*(0) or a K*(892) meson; we also measure B-0 -> f(0)K*(2)(1430)(0). For the K*(892) channels, we report measurements of longitudinal polarization fractions (for rho final states) and direct CP violation asymmetries. These results are obtained from a sample of (471.0 +/- 2.8) X 10(6) B (B) over bar pairs collected with the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) collider at the SLAC National Accelerator Laboratory. We observe rho K-0*(892)(0), rho(0)(K pi)*(0)(0), f(0)K*(892)(0), and rho K-*(892)(+) with greater than 5 sigma significance, including systematics. We report first evidence for f(0)(K pi)*(0)(0) and f(0)K*(2)(1430)(0), and place an upper limit on rho(-)(K pi)*(+)(0). Our results in the K*(892) channels are consistent with no direct CP violation.
