  We calculate the inclusive branching ratio for B--> X_s gamma, the inclusive
branching ratios and asymmetries for B--> X_s l+ l- and the anomalous magnetic
moment g-2 of the muon, within a minimal gauge-mediated SUSY-breaking model
which naturally generates a large ratio tan(beta) of Higgs field vacuum
expectation values. These predictions are highly correlated with each other,
depending on only two fundamental parameters: the superpartner mass scale and
the logarithm of a common messenger mass. The predictions for B--> X_s gamma
decay and g-2 are in somewhat better agreement with current experiments than
the standard model, but a much sharper comparison will soon be possible using
new measurements now in progress or under analysis. Moreover we predict large
deviations in B--> X_s e+ e- and B--> X_s mu+ mu- asymmetries, and somewhat
smaller ones in B--> X_s e+ e- and B--> X_s tau+ tau- branching ratios, which
will be detectable in hadronic colliders.
