Just one more question... what about the free electrons in the
observable universe? These certainly count as non-baryonic yet they
must be present somewhere. How can the number of free electrons can be
estimated and included in the count? Thanks, again.

The net charge of the universe is expected to be zero,
so for every electron there should be a proton
nearby (unbalanced charges will quickly balance through
attraction). The density figures will take this into
account.
