Hmmmm... well I agree with you on a few. In no particular order, here is my list:

• Vim
• perldoc/cpandoc
• Programming Perl and Learning Perl
• Git with Github
• strict and warnings
• Perlmonks and Stack Overflow
• Perl::Critic
• Windows 7/8 - sometimes Ubuntu
• Pencil and paper - necessary when designing and brain storming
• Firefox or Chrome

I could probably go on for a while, but those are my Top 10.
