A forerunner of most of the 'cool Pagan' characters on current TV was Willow, a character on the show "Buffy, the Vampire Slayer". The show is recent enough that you've probably seen it or heard about it, but I thought since you were gathering research, it would be good to present it.
Willow seems to be very comfortable in her faith. The show focuses on both the positive and the negative apsects of working with magick. (They made things that are normally introverted extroverted, in order to be more appropriate to a show that' action-oriented.) For example, Willow is able to bring her friend back from the dead. Conversely, she is also affected by the power she has, until it becomes a source of addiction to her.
I'm sure that there are plenty of other examples of Pagans in the media. That was just the one that came to mind most immeadiately.
Zephyr, 'that is so metal' is rapidly becoming my favorite phrase of praise!
