The best place for you to start looking is at the very beginning - check out Ovid's Web Programming with Perl course. That will get the basics out of the way, then you can come back and get further questions answered later. It would appear you are trying to bite off more than you can chew... learn to walk, then run. ;)
Best of luck with the course.
