Learning Perl, as others have said, is indeed quite good. If you've got bucks to spare, the O'Reilly Perl CD Bookshelf is also very nice. It's a bound copy of Perl in a Nutshell, plus several other books (including the venerable and indispensable Programming Perl) on CD. It's stiff at $80, but well worth it.

For #2, it looks like WinHTTrack is an offline browser which slurps a site, or portion thereof, to your hard drive. If by "your tutorial" you mean a set of pages on PerlMonks, then you may be out of luck. This whole site's database-driven, and I don't think they keep static copies of the pages anywhere.
