I use it all the time. All I can pretty much say is to just play around with Flash. As you said, all the tutorials suck. =/
However, here's a trick for remembering how to tween an object in Flash:
Funny Objects Love Moving in Tweens
Funny - Insert the first keyframe
Objects - Place the object
Love - Skip a few frames and put in the last keyframe
Moving - Move the object to the place you want it to go
In - Right-click in between the keyframes
Tweens - Create Motion Tween
