Seekers of Perl Wisdom would be the place for things like that. I'm not sure that I've ever asked outright for assistance polishing up code (Lord knows it could use it!), but I can't count the number of times that I have posted a problem, along with some code, and people have responded with solutions, as well as "....BTW, the subroutine following that could be better written as...". It might be wise, rather than ask, "how can this program be written better?", to ask a more specific question regarding a portion of code.
One thing that has helped me, and continues to help me, is reading posts which contain similar logic, or attempt to solve similar problems, but are syntactically cleaner/more efficient.
