mod-security

Very new to mod_sec

I want to block a UA string and I noticed there are a few types:

SecRule HTTP_User-Agent
SecRule REQUEST_HEADERS:User-Agent

What is the real difference between them?

My block:

SecRule REQUEST_HEADERS:User-Agent "perl" "phase:2,pass,msg:'Perl based user agent identified'"

Do I need to set a SecDefaultAction phase:2,deny,status:403,log,auditlog before that? Then any SecRule below that follows that action right?
