We present measurements of the flavor-changing neutral current
decays B -> Kl+l- and B -> K*l+l-,
where l+l- is either an e+e- or mu+mu- pair.
The data sample comprises 229 X 10^6 Y(4S) -> BBbar decays
collected with the BaBar detector at the PEP-II e+e- storage ring.
We measure the branching fractions
BF(B -> Kl+l-) = (0.34 +- 0.07 +- 0.03) X 10^-6 and
BF(B -> K*l+l-) = (0.78^{+0.19}_{-0.17} +/- 0.12) X 10^-6,
the direct CP asymmetries of these decays, and the relative abundances
of decays to electrons and muons.
