Apart from tons of useful info on the net if you have time and patience to look for it, this is to my knowledge the most accurate and complete 'hands on' book for Logic: 'Logic Pro 9 Advanced Music Production' by David Dvorin.
If you start now with one or two lessons per day you could be an Logic expert by Christmas!
And if you need help, just ask.
.... then there is also this:- http://www.lynda.com/Logic-Pro-training-tutorials/251-0.html ....
.... and/or this:- https://www.macprovideo.com/tutorials/logic-application
I find, that the two approaches compliment each other well. Have a look see ....
+1 Excellent Book! But start with the basics first.
Logic Pro 9 and Logic Express 9
Professional Audio Production
By David Nahmani
Be sure to check out David Nahmani's website!
Once you've mastered his book move on to the more advanced book.
Logic Pro 9 Advanced Music Production
Composing and Producing Professional Music
By David Dvorin and Robert Brock
I have both books. You can find them online.
They both come with companion DVD's that include the tutorial materials.
Yeah GTBannah answered your question with 2 great online choices. You will also find plenty of info on YouTube. Check out SFLogicNinja and others. You will find that a combination of reading a book explaining what to do and why while you physically do the work will have you up and running much faster.
