With a sample of 232x10^6 Upsilon(4S)->BBbar events collected with the BaBar detector, 
we study the decays of B mesons to ppbarh final states, where h=pi+,Ks,K*0 or K*+. 
We report evidence for the B->ppbarK*0 decay, with a branching fraction 
(1.5+/-0.5(stat)+/-0.4(syst))x10^-6, and for the B+->eta_cK*+ decay, with the branching fraction of 
Br(B+->eta_cK*+)xBr(eta_c->ppbar)=(1.57^{+0.56}_{-0.45}(stat)^{+0.46}_{-0.36}(syst))x10^-6,
and provide improved measurements of the branching fractions of the other modes of this type.
We also report the measurements of the charge asymmetry  consistent with zero  
in the B+->ppbarpi+, B0->ppbarK*0 and B+->ppbarK*+ modes.
No evidence is found for the pentaquark candidate Theta+ in the mass range 1.52 to 1.55 GeV/c^2, decaying 
into pKs, or the glueball candidate fJ(2220) in the mass range 2.2
