If the BH interior is supposed to contain no material things, all converted to gravitation, could this action occur from a fluid like substance composed of virtual particle pairs so closely held together that they exhibit particle exchange, therefore becoming an analogue to a bose einsein fluid? It seems as though there should be a "something" inside the BH from which graviation to act from, and if not from material things, then perhaps virtual things.

There is; the singularity. Note, not any singularity as defined by infinite density and curvature, but as defined by where our laws of physics and GR, are not applicable. 

could this imply that the singularity is a solid point or region of collapsed pair or pairs,  centered in a fluid of less compressed pairs?  When you say "infinite density", does that mean infinite in a numerical sense, or simply the highest value allowed with physical laws present in this universe, and that this density could theoretically be measured at some point?

We can make predictions based on our best theories, but they do have limits of applicability.
We simply don't have any predictive or observational evidence for the center of a BH.

All we know is that ( currently ) we have no evidence of any force that can counteract gravitational collapse, once neutron degeneracy can no longer counter it.
