Pramod, for a little bit more guidance...
Your "regular old CGI Perl scripts" are going to be ported to mod_perl
most easily using one of 2 different Apache/mod_perl modules:
* Apache::Registry
* Apache::PerlRun
To be _really_ simplistic about it, Apache::Registry is faster, but it
is more picky about the quality of your Perl CGI programs, insofar as
quality is a measure of ability to hold up in a persistent environment.
Apache::PerlRun is slower, but your scripts are going to handle a better
chance of working without modification. (Another aspect of how it's
slower is that you won't be able to take advantage of Apache::DBI persistent
database connections with Apache::PerlRun.)
Here are some helpful links from Sta's mod_perl guide online:
CGI to mod_perl Porting. mod_perl Coding guidelines.

Apache::PerlRun

Cheers,
Richard
