I suggest that you try reading the following books for a more well-rounded understanding of what Judaism is: To Be A Jew by Rabbi Donin, Gateway to Judaism by Rabbi Becher, On Judaism by Rabbi Feldman, Living Inspired by Rabbi Dr Tatz. They should all be available from www.amazon.com
There are also many authentic websites out there that you can rely on the information that is being posted. For example, wwww.ohr.edu , www.aish.org , www.torah.org , www.shemayisrael.org
