Yea, he has a lot of make-up remover for the wife it seems.

Batts, and vapour barrier are the way to go. It's cheap compared to heating loss over a year.

Think I should use unfaced batts and a separate plastic vapor barrier, or go with faced batts?

In terms of R rating, I imagine I should use R-13, since these are 2x4s?

Yes. Batts, and separate barrier is best for a seal. 2x4's should be R-15 value, but can vary from 11-15.
