O'Reilly Media opened the proceedings section of OSCON08. Not everything is there yet, but as I write this there are about a third of the Perl track, including Josh McAdam's Test Driven Development with Perl and Jim Brandt's Introduction to mod_perl 2 tutorials. Although Jos Boumans submitted his slides for "Barely Legal XXX Perl", you should probably wait until you can see it live. Finish off with Patrick Michaud's and jerry gay's Rakudo: Perl 6 on Parrot.
If you've already seen the Perl talks, I guess you could look at the other subjects too.
