  We examine the structure and dynamics of small isolated $N$-particle clusters
interacting via short-ranged Morse potentials. "Ideally preprared ensembles"
obtained via exact enumeration studies of sticky hard sphere packings serve as
reference states allowing us to identify key statistical-geometrical properties
and to quantitatively characterize how nonequilibrium ensembles prepared by
thermal quenches at different rates $\dot{T}$ differ from their equilibrium
counterparts. Studies of equilibrium dynamics show nontrival temperature
dependence: nonexponential relaxation indicates both glassy dynamics and
differing stabilities of degenerate clusters with different structures. Our
results should be useful for extending recent experimental studies of small
colloidal clusters to examine both equilibrium relaxation dynamics at fixed $T$
and a variety of nonequilibrium phenomena.
