The default behaviour in LaTeX is not to indent the first paragraph in a section. This follows publishing conventions --- just pick up a book at random and see that the first paragraph isn't indented, while subsequent paragraphs are.
However if you want to indent the first paragraph to match all the others, put this in your preamble:
\usepackage{indentfirst}
Use the starred version of the figure environment
\begin{figure*}
...
\end{figure*}
There is an unofficial theme here.
Use the \pageref
macro instead of \ref
.
\pageref{key}
The \pageref{key}
command displays the page number of where \label{key}
was used.
