  We apply a confining q\bar{q} potential to charmonium and open charm in order
to model wave functions and to begin studying structure. Results (in momentum
space) provide form-factor input to a four-flavor effective chiral Lagrangian
which models dynamics of charmonium in hot hadronic matter. Estimates are made
for J/\psi dissociation cross sections and rates within a fireball. Our study
attempts to improve on previous comover suppression models since it includes
gauge-invariant form-factor formalism constrained by quark-model phenomenology.
