Tell me about the history of Pesach

I live alone in a neighborhood with no Jews and no temple within walking distance. However, I would like to start practicing shabbat as much as possible. This presents small difficulties though. For instance, do I need two loaves of challah bread when the other will most likely be wasted? Or since one of the prescribed activities is socializing with your family and friends, is it acceptable for me to have phone calls with them or would that be melacha? Basically, my question is: is it possible or advisable to celebrate shabbat by yourself?

If I do not believe in heaven is that against judaism?
