Your Perl version is the least of your problems. RH 7.2 was end of life'd around three years ago. Upgrade to a more recent OS and you'll more than likely get a more recent Perl to boot.
And as to your questions: Yes, but there's a newer version of CPAN.pm than ships with 5.8.8 I believe. And I personally tend to keep my own "application" version of Perl compiled separately from source independent of the OS' copy. That also ensures that updates to the OS are less likely to muck about with the "production" version of Perl.
