I think you can definitely go for Modern Perl. While this is not in my opinion a book for pure beginners, or let me rather say that you will better benefit from it if you have some basic knowledge of Perl (BTW, the name of the language is Perl, nor pearl), but a basic knowledge of Perl will be sufficient to start with it (and you definitely have the basic knowledge that I mean), and it will help consolidate your knowledge.

Intermediate Perl has a somewhat higher prerequisite. In my view, it would make sense to go for Intermediate Perl after you've gone through Modern Perl.
