AS2 or AS3?

Hi all

Very green newbie to Flash and AS here, Ive recently started playing with CS4, and want to learn Actionscript. Sorry, got 3 questions here:
Is it better to learn AS2 first or skip it completely and start with AS3 right off the bat?
Is it better to learn Flash completely before I start learning AS at all?
Any fool-proof very simple-to-follow tutorials out there about the basics of CS4 and AS3?
I have found a few but they are all either at an advanced level or aimed at users who have previous experience with Flash CS3 and AS2.
