If you have access to Perlmonks, you have access to a manual. perlman:perl. All the manpages are here.
Also, you might want to check out Martin Fowler's excellent book on dealing with legacy code, Refactoring. Basically, you can't fix code until you understand it, and some legacy code is not comprehensible as written. Refactoring allows you to gradually improve existing code in small steps, checking along the way to make sure you don't break existing functionality.

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).

or How to display code and escape characters
are good places to start.
