I haven't been actively involved in IPv6 training for a while now, but the folks at the Deploy360 program are collecting lots of good resources:
http://www.internetsociety.org/deploy360/ipv6/ Hurricane Electric, one of the pioneers in v6 commercial networking has also taken on the task of educating users; they even have an informal certification program:
http://ipv6.he.net/presentations.php and
http://ipv6.he.net/certification/ You can use one of their tunnels to get a connection to the IPv6 Internet, if your current ISP doesn't yet support IPv6 (and sadly, most don't).
That should be plenty to get you up to speed on IPv6. . .
