I'd recommend checking out the Core Logic 101 which is the perfect place to start your Logic journey:

Isn't Core Logic 101 essentially the Logic 8 version with a few bits of Logic 9 thrown in?
I would think that someone new to Logic as of version 9 would want Logic 9-specific content.
The Groove 3 Logic 9 Explained is
all new content and not a repackaged version of the Logic 8 tutorial.
Wow... That's both unfair and not relevant IMHO...
I don't know if you're familiar with the Apple Certified Guide : Logic 101: Introduction to Logic Express 8 and Logic Pro 8 book by David Nahmani and the book for Logic 9?? (You linked to the later above). The content is exactly the same aside from a few minor changes throughout the book to reflect changes relevant to Logic 9... However, I had to pay full whack to get the new edition... I'm not complaining as I feel it is a good book and of course as an Apple Certified Trainer I use it as the basis when teaching Logic Certified courses.
The macProVideo.com Core Logic 9 101 is the Logic 8 101 with additional videos and some replaced videos & content relevant to any changes in Logic 9. The interface and 95% of the functions etc are exactly the same otherwise! There's no need to reinvent a highly acclaimed and popular wheel just for the sake of it.
You know macProVideo charge existing owners of the Logic 8 101 only $5 to upgrade to 9... we'd rather do that and make less money than create new content for the sake of it in order to convince customers they "need" a brand new tutorial when the existing one ticks all the boxes.
Aside from that Flex Time and other major additions are either covered in their own tutorials or in the free "Logic 9 first look" tutorial:

I didn't reply to (and answer) Mark's original question to promote macprovideo tutorials... I replied in order to explain the concept of Chase MIDI note events.
@ Mark, there are plenty of options available as you can see from this discussion. I hope you find the one's that suit your learning style and needs best. I'd like to add that an additional option not yet discussed is one-to-one training or attending the 3 day Logic 101: Introduction to Logic Express 9 and Logic Pro 9 course at your local Apple Authorised Training Centre. At the end of the 3 days you have the option to take an exam which will give you the title of Apple Certified Pro in Logic 9 level 1. Although all the content is based on the Logic 9 book by David Nahmani, I've had students who feel they've gained a lot from attending course over reading the book at home. Of course this option is more costly, but some people appreciate the intensive hands-on approach...

Otherwise, all the links to videos and books and using forums like this one will, I'm sure, be of huge benefit in helping you get the most out of Logic!
Good luck!
