Nice example site. And I can think of a couple of different ways I’d have gone at setting it up- which illustrates the pro/con of EE. It’s HIGHLY flexible and there’s almost always several different ways of approaching site creation. Thus there isn’t a simple 1,2,3 tutorial on how to create a specific site.
What I’d suggest- try out one of the trial options- either the Core or the hosted trial would likely work for the type of site you want to practice on.
Then- read the Getting started guide- and I’d read the section on EE urls and the templates and tags overviews.
That will give you a feel for the core logic. Then I’d run through the Quick start tutorial- create a weblog, add some content.
Once you’ve got a feel for the basics, it’s time to think about structuring the site- and at that point, the big decision will be how you break things out into different weblogs and categories- check this wiki article for an overview of what goes into that decision. Also- the forums are great for giving advice on a specific setup.
I know it sounds like a fair bit of work to get ‘up to speed’- but it’s worth it. Once you have a feel for how it all works, it’s much easier to start planning how best to structure things for your particular needs.
Make sense?
