There are some good books reviews on this site, check them. There are also a lot of nice free perl books on various websites, check for instance http://www.techbooksforfree.com/perlpython.shtml ; particularly "extreme perl" and "beginning perl" which are very nice.
About the IDE : it all depends the platform you're using. Open Perl IDE (on sourceforge.net) for Windows is really great (integrated debugger and documentation). On Linux and Mac OS X I use exclusively NEdit with tons of macros I wrote, but many will tell you about Emacs, Eclipse, etc.
