  We study a two dimensional, two-band double-exchange model for $e_g$
electrons coupled to Jahn-Teller distortions in the presence of quenched
disorder using a recently developed Monte-Carlo technique. In the absence of
disorder the half-filled system at low temperatures is an orbitally ordered
ferromagnetic insulator with a staggered pattern of Jahn-Teller distortions. We
examine the finite temperature transition to the orbitally disordered phase and
uncover a qualitative difference between the intermediate and strongly coupled
systems, including a thermally driven insulator to metal crossover in the
former case. Long range orbital order is suppressed in the presence of disorder
and the system displays a tendency towards metastable states consisting of
orbitally disordered stripe-like structures enclosing orbitally ordered
domains.
