> Purely out of curiosity, does anyone know what form of silver makes
  the image of a salt print? Is it elemental silver particles that
  appear different shades of brown due to their size, or is it a
  silver compound?

Until it is toned, what is visible is metallic silver.

> Also, the color seems to be affected by the specific paper that I
  have used. What causes this?

Depending on what's in the paper, but I think that sort of thing is
generally difficult to figure out exactly what is doing what.
