I'm not sure there are exact mappings between vim and emacs, since they use different concepts.

I have several macro-like functions which I've defined for Perl programming convenience. For example, this creates a new sub:
(defun perl-sub (name)
"Insert a new subroutine"
(interactive "*sName: ")
(insert "sub {\n\n\n\n}\n")
(previous-line 4)
(indent-for-tab-command)
(insert "my () = @_;")
(search-backward "sub ")
(goto-char (match-end 0))
(insert name)
(search-forward "("))
It prompts for the sub name, then outputs a bare subroutine with "my () = @_;" on the first line and putting the cursor inside the `my' list. You can then call this function with `ESC x perl-sub'; you could also bind it to key command, for example (global-set-key [f3] 'perl-sub), then you can just hit the F3 key to do it. Modifying this to output Data::Dumper stuff (good idea) would be straight-forward.

I'm not sure what document templates are for. You could easily include a file with `C-x i', though, or use the above "macro" technique.

For indenting, I have this inside (custom-set-variables):
'(cperl-close-paren-offset -4)
'(cperl-continued-statement-offset 2)
'(cperl-indent-level 4)
'(cperl-indent-parens-as-block t)
'(cperl-label-offset 0)
'(cperl-tab-always-indent t)
That gets pretty close to (tab) indenting consistently with what I think is the style seen in most Perl books and documentation.

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).
