The book you need in "The Camel Book": Its an O'Reilly publication, "Programming Perl by Larry Wall, Tom Christiansen & Jon Orwant - my copy is the 3rd edidtin, dated 2000, so there are probably more recent editions. Its well written and organised and, equally important, has a whole chapter on Perl regular expressions, which are not the same as,e.g C or Java regexes.
I also know very little perl, but this book, together with an example SA plugin, were enough to let me write an SA plugin for doing lookups on a PostgreSQL database containing my mail archive I use this plugin to whitelist mail from anywhere I've previously sent mail to). Martin
