Great list, Phillip.

Regarding number 5, a bit of shameless self-promotion: my 7-week web editorial class at Ryerson in Toronto is an overview of what web editors need to know and a good way to meet other people with the same interests. ryerson.ca/ce/magazine

There's also my blog: magazinesonline.wordpress.com

And if you want to meet more people in the industry, get in touch with some and offer to take them out for coffee to ask them questions. Free coffee will get you a long way. :)
