It depends on what document you write.

> \documentclass[11pt,a4paper]{article}
> \parindent=5mm
> %\usepackage{fancyhdr}    %%% -> this package is used to customize headers and footers, if you don't want to change them don't use this package.
> %\usepackage{fancy}       %%% -> (fancy cross ref.) to customize cross ref., if don't want customize them don't use it.
> %\usepackage{pst-node}    %%% -> from PSTricks package, to draw an image using PostScript (see documentation)

Below is example document with many mathematical formulae and include external graphics:
<example file="ex1.ltx">
\documentclass[11pt,a4paper]{article}

\usepackage[utf8]{inputenc}
\usepackage[spanish]{babel}
\usepackage{amssymb}
\usepackage[intlimits]{amsmath}
\usepackage{graphicx}
\usepackage{geometry}
\geometry{a4paper,text={6.75in,8.5in},topmargin=0in}

\begin{document}
% Texto
\end{document}
</example>

General advice #1: start with simple preamble (like in the example) and
add packages only when know what they provide.

General advice #2: READ [PACKAGE] DOCUMENTATION, e.g. if you use TeX
Live distribution run in terminal (command prompt):
texdoc geometry
or
texdoc [package name]
to read package documentation.
