The Declaration of Independence does indeed have four
parts.

The parts come in this
order:

FIRST, the preamble basically says why the
Continental Congress wrote the Declaration of Independence.  It states that when it
becomes necessary because of injustice, a group of people should be able to state their
grievances and take action.  The preamble is the first item in a document almost 100% of
the time - thus, it is called the PREamble, or "explanatory stuff that comes first".
 Other words for a document's preamble are "preface", like we have in books, or
"introduction", like when a speaker is introduced before his
speech.

SECOND, the Declaration of Natural Rights states
that all human beings were given certain rights by their Creator and that the government
should protect these rights.  

THIRD, the List of
Grievances, gives a run-down of all the rights that the Continental Congress believed
the British government, and King George III in particular, has
violated.

FOURTH and last, the Resolution of Independence
says what the Continental Congress has decided to do about all the aforementioned
things.  In this section, the United States informs Britain that it has decided to
become its own country.
