I was just informed that I need to learn Actionscript for a project. I don't even have flash on my machine yet and I need to give a presentation on tuesday on how we will be building this.
So, its time for a little cramming, where can I study up on some actionscript?
I would suggest to download the Flex 3 SDK and play around with it. Ideally you'll want to install the Flex Builder trial in which it is possible to create Flex and ActionScript 3 only projects.
If you need books, there's Essential ActionScript 3 and the ActionScript 3 Cookbook.
There is also a good video tutorial series on lynda.com
To add to Chrisophe's answer, don't forget the language reference:
It's like javadoc, but for Flex. :)
Also, if you can get the company to spring for it, a training course could be helpful. I recently did one in DC provided by Figleaf and it was quite good. (Obviously this won't be helpful right now like you need, but if you are going to do a project in Flex it may help in the long run).
Flex Component Explorer will get you started quickly.
Adobe Help Documentation is also a good reference.
Other Tips: Don't forget to install the Flash Player Debugger. The Flex Style Explorer is useful is you're going to do Flex.
Was going to say that, but you beat me to it!
Here's the specific thread Useful AS3 Migration Books / Resources on gotoAndLearn about AS2 to AS3 migration -- books, tutorials, resources.
I ran across Tour de Flex a couple days ago. It's a demo that showcases all the Flex controls, with cross-references to source and references. It's a great way to get an idea of the resources available, and how to use them.
Too late now, but it's full of great examples for a presentation - you might have been able to carry off the whole thing just with this.
If you're trying to learn object-oriented programming in ActionScript 3.0, you might also consider O'Reilly's "Lost ActionScript 3.0 Weekend" video. It's an 11-hour training course with Colin Moock, author of Essential ActionScript 3.0:
May I suggest this website? http://tutorials.as3.ca it is a compilation of the best AS3 tutorials on the internet, organized by category & difficulty level. It might not be a pretty site but the content is golden! It is a work in progress, still adding tutorials weekly.
Thanks!

Online sources. Republicofcode is good for actionscripting. Developphp gives a deep understanding of using Flash.
