Some of the best learning comes from watching the video tutorials here on the Mocha site + taking a few hours and trying things out on your own.

One video that will get you on the right path (starts at about 7:30, inserting a tattoo onto a face):

And then for the glowing skin, you can try a tutorial #140 “Sub Surface Skin” on the videocopilot.net site.
