For beginning you can start with basics. Build up enough energy then you may work with healing and protection spells. Pretty easy ones to start with and less backfire dangers. But before any spells you may first study it and gain the knowledge then you may cast spells.
Also about.com is a good site for all kinds of info. Once there, put Wicca basics in the search bar. It will take you to basics of magick, too. I was on it for hours just looking and reading. And copy and pasted a lot of things to my computer.
