There are several services in the synagogue during Shabbat. The first is held to mark the beginning of Shabbat on Friday evening, which is usually attended by the men, and the whole family may attend the Saturday morning service.
Every Shabbat a different portion or Parsha of the Torah is read in synagogue. The Union of Reformed Judaism site has an audio commentary on the weekly parsha (commentary starts after the 40 second introduction).
The Prayer book used is called a Sidur.
The National Jewish Outreach Programme in America has an outline of the Shabbat services.
The Torah scroll is held up before reading
