I'm sure I'll come across all the different ways of going about things anyway the further I get in to Perl.

Actually, probably not. Perl has lots of nooks and crannies that most people never need to venture into. But that's OK. From the Programming Perl 3rd ed. preface:

Most important, you don't have to know everything there is to know about Perl before you can write useful programs. You can learn Perl "small end first". You can program in Perl Baby-Talk, and we promise not to laugh. Or more precisely, we promise not to laugh any more than we'd giggle at a child's creative way of putting things. Many of the ideas in Perl are borrowed from natural language, and one of the best ideas is that it's okay to use a subset of the language as long as you get your point across. Any level of language proficiency is acceptable in Perl culture. We won't send the language police after you. A Perl script is "correct" if it gets the job done before your boss fires you.
