The angular analysis of exclusive rare B-meson decays via intermediate vectormesons V into 4-body final states of two pseudo-scalars P_1, P_2 and a pair oflight leptons l = e, mu offers a large set of observables. They can be used totest the electroweak short-distance couplings in the Standard Model and tosearch for New Physics. The two kinematic regions of low and high dilepton massdepend on short-distance physics in complementary ways and can be expanded inpowers of Lambda_QCD/m_b. These expansions guide towards suitable combinationsof observables allowing to i) reduce the hadronic uncertainties in theextraction of the short-distance couplings or ii) test the lattice QCD (B -> V)form factors in short-distance independent combinations. Several suchpossibilities of CP-averaged and CP-asymmetric (T-even and T-odd) quantitiesare presented for B_d^0 --> K^*0 (-> K pi) l^+ l^- and time-integratedCP-asymmetries without tagging for (anti-B_s, B_s) --> phi (--> K^- K^+) l^+l^- decays in view of the latest B-factory and CDF results and the forthcomingLHCb measurements.
