I agree; I just suggested 1296 trials to start with for a sanity check.

The ply at which variance reduction is performed will affect only the
rate of variance reduction, not the end result.  Variance reduction at
any ply is very helpful, and depending on the other settings, generally
saves at least an order of magnitude of trials.

Yes, I think this is helpful (which is why I suggested setting the
seed, so the dice will be matched).
