Pagan is a general term for any religion that is not Christian, Jewish, or Islam.
And Baha'i.

Some would not include any of the major world religions like Hinduism and Buddhism as pagan.
My snarky Buddhist friends would say, "Buddhism is a philosophy", XP
Hinduism strikes me as a pretty "pagan" religion, regardless how you frame it. Granted, I consider Tibetan Buddhism pretty pagan, too, what with the bodhisattvas. Meh.

Once you are initiated into a proper coven you are Wiccan. To be a practicing Wiccan you do need to celebrate the sabbats with the proper rituals done with your coven. You can not practice Wiccan rituals correctly without a coven. All Wiccan rituals require the use of witchcraft. As a Wiccan you use witchcraft at every ritual. You can not be Wiccan without being a witch, but you can be a witch without being Wiccan.
To re-emphasize what you have already said (thanks), Wicca is an orthopraxic religion, where the action is what defines/unifies the religion, not so much the belief. Further, in that all Wiccans really are priests, it makes sense then that they would need more training and indoctrination than your run of the mill congregation.
