Wicca is a religion. Therefore you either are or aren't Wiccan. Just do a google search entitled "Wiccan beliefs" or something along those lines. Just stay away from the Christian sites. They're wells of misinformation.
I think that really depends on you and how the beliefs balance. There are some people who are wiccan and another religion, and there are those who would say that you cannot be. Since it is what you believe that is the key, only you can make the final call. Just be prepared that some people in both 'camps' will say you have to chose.
Also remember that you can be interested and a practitioner of magic and spells and not be wiccan, wicca is just one belief system within the spectrum of beliefs.

Wicca isn't spellwork, it's a religion which happens to incorporate magical practice into the religion itself. Wicca is not something you are born being, you have to actively decide you want to convert to the Wiccan religion. You become a Wiccan by studying the religion, practicing the religion, and dedicating yourself to the Gods of Wicca.
You don't have to be Wiccan in order to practice magic. Anyone of any religion can do that. So don't worry about whether you are Wiccan or not unless you decide that you want to join the religion
