I suggest your first point is incorrect, but your second is correct. 

Whether we should read Junia or Junius (nominative singular, female or male) is a question of textual criticism. It depends how Junias (genitive singular, the actual word in the text) is accented, one version being the genitive singular or a female Junia and the other being the genitive singular of Junius. I suggest that question has been settled in favour of Junia, a female. I personally am impressed by the evidence that Junia was a common female name at the time, whereas Junius has little evidence as a then current male name.

However, you are correct, Pandora, IMHO, that the purport. the theological significance of Paul calling her an apostle is up for debate. 

What is not debatable is that prejudice is required to explain the transition of Junia to Junius in the scripture because of the delusion could not have called a women, and apostle, as he did. 

Once cannot conclude from this either way re ordination.
