The laws are either explicitly explained or refered to, sometimes vaguely, in The Bible.
As there are over 600 of them I cannot sit and show the origins of them. The purpose of the commandments (mitzvos) are to enhance the life of the practitioner.
There are two sets:
The core guidelines for Judaism are called mitzvot and are found in the Torah.
The laws for Judaism, which are called 'halachah', are found in the Talmud.
Hebrew society (the society in ancient Israel) was based upon the Torah-laws and the covenant with God.
Some of the results:
There was always a learned class among the Israelites, and virtually all men and boys (and a good percentage of women) could read and write. A portion of each day was spent praying, and another, larger part of the day, was spent studying Torah (by a good part of the populace). Religious questions (and torts) were brought to one of the many Rabbis or Jewish courts. Having a large family was an ideal, as was welcoming guests into the home, giving charity, and other forms of kindness. A portion of crops were given to the poor. The calendar year was replete with the Sabbaths and festivals; and blessings were said before and after eating and on many other occasions.
In brief, there was no such thing as a secular part of life, since the Torah's laws cover every form of activity, including business.
The purpose was, and still is, for the Israelites (Jews) to serve God, in keeping with their covenant with Him. See also:
To enable us to serve God. The Hebrew Bible reiterated the teachings of Abraham (Talmud, Yoma 28b) and codified their exact details; and at Mount Sinai, the Israelites accepted as obligatory what had until then been national custom. The Torah and Prophets have shaped our ways of thinking and provided a national legal code.Link: More about Abraham
Israelite society wasn't perfect. We are human; and as seen in the Prophets, there were times of backsliding and various pitfalls. But to the extent that the people kept their national laws and tradition, the society was exemplary and created a model which has influenced the Western world down to today.

There are 613 mitzvot (guidelines) in Judaism, all of which appear in the Torah (known by Christians as the Pentateuch). Judaism also has a fully developed set of laws, similar to those of any country, these laws are called 'halacha' and can be found in the Talmud. For a complete list of these commandments, please check the related link or Google: 613 mitzvot.
Before the age of 12, Jewish girls observe the laws of Judaism as part of their preparation for adulthood. Once they reach 12 years old, the Torah obligates them to keep its laws, which include Shabbat-observance, eating only kosher foods, modesty, and many other laws.
Judaism has a lot of laws, but actually concerning the law, Judaism really only has two rules: study it and obey it. (Studying means both learning pre-existent laws and trying to further understand and interpret.) As for mortality. Judaism holds that mortality is part of the human condition since Adam's departure from the Garden. Judaism implores people to accept their mortality, but to consistently push to extend life and improve life in this world. Judaism also teaches that when the Messiah comes, eternal life will be granted to the righteous.
It depends entirely on what you are comparing Judaism to. If you are comparing modern forms of Judaism to ancient forms of Judaism, there are several differences. Judaism has had to adapt to not having the Great Temple in Jerusalem and to being mostly in countries where Judaism was not the majority religion. As a result, a number of rules specifically dealing with the Great Temple are no longer followed. Additionally, the Rabbis wanted to protect the observance of the Torah Laws by creating additional, more restrictive laws to prevent unintentional breaking of the Torah Laws. Finally, there was also the recent development of Liberal Judaism, which represents a fundamental shift in Jewish observance and belief. Using modern, and non-Jewish ideas to influence the way in which Judaism should develop.
A Rabbi or a Cantor (or anyone for that matter) can interpret and teach the laws of Judaism.

Reformed Judaism believes that the Bible is the main source for the rules of Judaism.

The Torah is the key to Judaism. It contains the history of Judaism, its morals, laws, ideology and outlook.
