as for 2 & 3...

2. You're printing a quote-delimited string that itself contains quotes...you could either change the quotes in your string to single ones, like this...
print "<META HTTP-EQUIV='Refresh' CONTENT='whatever'>"
or escape the double quotes thus...
print "<META HTTP-EQUIV=\"Refresh\" CONTENT=\"etc.">";
or change the delimiters...
print '<META HTTP-EQUIV="Refresh" CONTENT="etc.">';
or use a "HEREDOC"...

print << "HERE";
<META HTTP-EQUIV="Refresh" CONTENT="stuff">
HERE

3. You could either read in a "straight" html file and print it back out again, or check out one of the templating modules such as HTML::Template. Both methods would allow you to play with your HTML layout in dreamweaver (although personally, I prefer / would recommend writing HTML simply in a text editor).
