Browsing my link page, I found this website that teaches you a lot about wordpress and among other articles, it has a video tutorial. So I checked it out and watched some of the videos and I saw that you can learn a lot. Here it is:
Welcome to the WPtuts+ WP101 tutorial series, the perfect beginning spot for those just getting started with WordPress! It's also a valuable resource for designers & developers who are teaching your clients & colleagues!
The videos are in English, though. And I finally implemented the menu thing in my theme so now the nav bar is with that tag.
