Choosing the extension of your CGI scripts depends on your web server configuration. Without knowing more about that, it's difficult to assist you.
Most issues are tangentially related to Perl (but lots of people here do have experience with these sorts of things). The first resource I ever used is this FAQ (don't let the name throw you).
You will probably want to start your script with:
#!/usr/bin/perl -wT
use strict;
use diagnostics;
use CGI;
I have not read your book. If it does not explain strict and CGI.pm, it is probably incomplete and may lead you astray. We can provide you with links to more complete information if this is the case.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
