Yup, you are correct Jay. For the overall color, you can click the button on the right and apply your Photoshop color texture file. I just don't know how it will affect the sub-surface skin scattering effects because fast_skin has its own three native individual color attributes in epidermal, subdermal and backskin so applying an external Photoshop color texture file would probably nullify those and you will lose the SSS effect. I dunno...have you ever used misss_fast_skin on a face before the UV technique you mentioned? I checkout ZBrush and that direct 2.5D texture applying technique plus ability to touch up to and from Photoshop is a million times better! :-)
