Lessee, what's some good tips for flash... Don't be afraid to use lots of layers, though when doing that, make sure you label your layers in a way you can easily remember. Tweens are simple ways to get your objects from point A to point B on the stage: Classic Tweens are for basic movement, rotation, and scaling, Motion Tweens are like classic tweens, but give you more control over individual transformations, and Shape Tweens are interesting, but finicky and personally not suggested.

When using a Classic Tween, you can add another layer and make it a Motion Guide, which acts as a path for the Classic Tween to follow. Can be handy when you want an object to follow a specific path, and you don't want to add a keyframe on every frame.

It can be helpful to add a layer when you first start animating, and using it to mark specific points in your animation that you want to remember. Say, if you have something happening at frame 60, just add a keyframe there, and under the properties tab, under label, type in "//" and whatever you want to comment.You can comment without the // though, it's not too big of a deal.

Ctrl + Shift + Scroll Wheel = zooming in and out of the stage. So much easier than the zoom tool.

Holding Shift while making an object will keep the object proportionally equal. Perfect squares and circles, etc.

When using Free Transform on an object (right clicking on an object, then selecting Free Transform), the white dot in the center of your object is the point of rotation. If you've drawn an object that you want to pivot around a certain point, just move the white dot to where the object should pivot. You should define these after you've created a Tween, but before you start inserting Keyframes.

I'm not sure if these are going to be too helpful; I'm decent-ish at flash, but bad at drawing, so I've never tried a character animation in flash.

That is helpful! I planning to do like a 10 second animation to a song I completely adore, been playing around in photo shop ( thus the new icon ) but its been years since I've honestly taken my hand to Flash, so its a bit of reteaching myself, picking up new tips and etc.

Layers...I love layers, but I really need to remember to label them, I have that issue in every program I use.

Yay for being helpful! Hah, yeah, naming layers can be a bit of a chore, but it's so handy when you go back and it's not just Layer 1, 2, 3, etc.

Oh, sound. o.o Sound can be really, really finicky. For the sake of sanity, when adding in sound, (keyframe, properties, sound, selecting your sound), make sure to select Sync: Stream. Otherwise, every single time you pass that keyframe when playing the animation, the sound will play, and continue to play, even when the timeline has stopped. @_@ The only way to stop the sound is by muting and unmuting, Ctrl + Alt + M

Also, when exporting the animation, to get any sound quality, you'll need to go into the Publish settings, go to Flash, and then change the Audio Stream and Event options to a higher bit rate, and best quality. Otherwise, it'll just sound awful. D:
