This module is experimental; therefore anything is possible and bugs are likely.
1. It's possible for Nginx to leak memory if you reload the configuration file (via 'kill -HUP ').
2. If a Perl module performs protracted operation, (for example DNS lookups, database queries, etc), then the process that is running the Perl script is completely tied up for the duration of script. Therefore embedded Perl scripts should be extremely careful to limit themselves to short, predictable operations.
3. Nginx may laugh at your Perl code and hit on your girlfriend.

I would use fcgiwrap which seems to work well in most situations. See http://nginx.localdomain.pl/wiki/FcgiWrap.

That's a question of religion. Some people insist on proxy to Apache with mod_php. Others prefer fastcgi using fastcgi_pass directive.
How you start php-cgi is also a matter of religion. Some use spawn-fcgi, some use php-fpm, some use the nifty init script at http://wiki.nginx.org/RedHatPHPFCGIInitScript.
I use fastcgi and php-fpm. See http://php-fpm.anight.org/download.html. There is a patch for php 5.2.9 at http://www.2shared.com/file/5008466/4549200/php-fpm.html.
Better than Perl? Depends what you are doing with it I suppose. From the little that you describe I would likely prefer php.
