A bunch of things I like, in no particular order.

Vimcasts: http://vimcasts.org/ (And keep your eye out for Drew's forthcoming book: Practical Vim.)

Vim University: http://vimuniversity.com/

Coming Home To Vim: http://stevelosh.com/blog/2010/09/coming-home-to-vim/

Efficient Editing With Vim: http://robertames.com/files/vim-editing.html

Why, oh WHY, do those #?@! nutheads use vi?: http://www.viemu.com/a-why-vi-vim.html

Your problem with Vim is that you don't grok vi: http://stackoverflow.com/a/1220118/26702

Vim anti-patterns: http://blog.sanctum.geek.nz/tag/anti-patterns/

Beginners should really start with vimtutor (just type "vimtutor" in your shell), and go through it a couple of times.

This is also useful:

And when you're done with those, come to #vim on freenode. You can learn a hell of a lot about vim by just idling there. Of course, you'll learn even faster by asking questions.
