Final Cut Express - best way to learn

I am just slightly familiar with digital video editing - in the past I played around with Pinnacle's software on a PC. I have a couple projects now where I'd like to use Final Cut Express (I have the older version 1). I have figured out the very very basics - basically getting a video in from a camera successfully, and then saving the project to disk. But I'd like to learn to really use this program well.

I know if I mess around with it, I will eventually figure it all out - but I was wondering if there are recommended tutorials, Web sites, etc. that you folks have found helpful in learning this program in a more systematic manner.

As a secondary question - is it worth upgrading to FCE 2? I got FCE 1 for next to nothing, so I'm not averse to spending $99 if it's a worthwhile upgrade.

Thanks for your help!
