Assuming you're on Mac you'll need to set up a decent .vimrc to enable syntax highlighting, indentation and some other bits. Vim is a different beast depending on how it's set up.

The built in tutorial is a decent place to start. I think that's the only thing I did apart from editing code. It takes a while to get over the hump but it's worth it.

I also suggest remapping your CAPS LOCK key to ESC. PCKeyboard Hack is free and simple to set up for that purpose. I've never liked the role of ESC in vi. It's too far away from the home keys.

If you learn to love the efficiency, I'd suggest looking at Komodo Edit or another editor that has vim key mappings. I prefer Komodo because it's vim plus code completion (I'm not aware of a vim solution for that) and a bunch of other bits that will save time.
