If you are beginning with Live, I would still suggest you check out the Core Live 8 101 tutorial, and also the Live 8 501 and 502 (working with Live 8 Level 1 and 2 courses). These tutorials are relevant for the most part to Live 9 and go over topics that are not covered in the Live 9 100 and 101 tutorials.
The Live 9 100 tutorial covers the new features introduced in the latest version of Live: the new browser, the audio to MIDI functions, the new Glue compressor, etc. Live 9 101 is all about how to use Live 9 on stage, in a live context. As Gary suggested, both are highly recommended! :)
