Unfortunately, I can't answer about the Ben Nye makeup and breaking out. Primer might help, though. Look up tutorials for "no makeup" makeup on YouTube for pointers. My favorites on YouTube are LisaEldridge, Pixiwoo, and Gossmakeupartist.
You're probably going to look great with blended contouring, subtle eye liner, mascara, and a very natural lip color. I would recommend taking your contouring color through your eye socket for some additional definition/depth. Depending on your foundation's finish, setting with some powder might help, although I would keep to the T-zone only. Korra is an athlete, and her skin shouldn't look cakey. Hope this gives you an idea or two. Good luck!
