Please don't take offense at my reply, there is no such thing as too novice for this forum, people here are happy to help those of all experience.
I'm not trying to stray from your question, but this is a discussion forum and I have to call it as I see it.
To be honest (and without trying to get into what's good and bad) I find most of this photographer's images to be tremendously over processed. By that I mean that they have been retouched (photoshopped) beyond a level that you would get for a magazine cover and in doing so made to look like plastic. This seems to run through her 'style' to varying degrees. I expect she's also retouching backgrounds.
I've copied a couple of examples of this to my web site to save trying to somehow reference them in her flash gallery.
Images removed due to bleeding heart liberals who think they are the guardians of all that is right and just in the world. Instead please do go to the trouble of figuring out the link above (unless someone decides to fix it) then trolling through a few flash galleries to see some extreme examples of making people look alien and plastic.

I'm not saying they or she is bad, they're obviously the work of a skilled person. While it's obvious to me she does know how to compose and light a portrait I'd also have to say that real people have pores. If I processed somebody's portrait this much I'd actually expect to offend them.
She's boosting colour, working particularly on peoples eyes and removing nearly all blemishes from the skin.
I think my original answer was wrong, the answers you seek will not be found just from lighting and good exposure, to truly emulate the style of this photographer I'd suggest a long course learning how to use Photoshop.
If you want an example, take any reasonable portrait of your own and post it here to the Photoshop challenge forum asking that someone do a slightly over the top glamour retouching job and explain to you the steps in how they did it.
