  We study in some detail the spectral phenomenology of models in which
supersymmetry is dynamically broken and transmitted to the supersymmetric
partners of the quarks, leptons and gauge bosons, and the Higgs bosons
themselves, via the usual gauge interactions. We elucidate the parameter space
of what we consider to be the minimal model, and explore the regions which give
rise to consistent radiative electroweak symmetry breaking. We include the
weak-scale threshold corrections, and show how they considerably reduce the
scale dependence of the results. We examine the sensitivity of our results to
unknown higher-order messenger-sector corrections. We compute the superpartner
spectrum across the entire parameter space, and compare it to that of the
minimal supergravity-inspired model. We delineate the regions where the
lightest neutralino or tau slepton is the next-to-lightest supersymmetric
particle, and compute the lifetime and branching ratios of the NLSP. In
contrast to the minimal supergravity-inspired model, we find that the lightest
neutralino can have a large Higgsino component, of order 50%. Nevertheless, the
neutralino branching fraction to the gravitino and the light Higgs boson
remains small, < 10^{-4}, so the observation of such a decay would point to a
non-minimal Higgs sector.
