Wicca is a religion first, not a magical path. Wiccans live their life by the Wiccan Rede 'Eight words the Wiccan Rede fulfill, An it harm none do what ye will.' which is similar to the 'golden rule' basically if no harm is brought upon another it's fine. this can get tricky as some people interpret harm differently. for example, you cast a love spell over someone, you're imposing your will over theirs, and therefore doing harm. you kill animals for the meat, doing harm. you eat too much junk food, you're doing harm to your body. even smoking, drugs, alcohol, tattoos, piercings, and so on, are somehow effecting your body in a negative manner, so some Wiccans stay clear of them. one of the biggest arguments in the Wiccan community is eating meat. some believe one must live in balance, and since humans are omnivorous, occasional meat is fine, don't overindulge though. the second group feel killing an animal is against the Rede, so they're vegetarians. some take it a step farther and become vegan. point is, it comes down to your interpretation of 'harm none'.
the second thing Wiccans believe in is the Rule of Three, or Karma, anything you do, good or bad, will return to you three times over.
Wiccans also celebrate the seasons and nature more than spell casting, at least the ones i've met do anyway. there's a lot more thought put into spell casting, thanks to the above rules. example, a healing spell, while this would be good, if the person doesn't want it and you cast anyway, you're doing bad.
i'd look for a beginners guide by Raymond Buckland to give you more information on the path and figure out what Wiccans do compared to other Pagan branches.
