Need help with mini movies in Image Ready and Photoshop

I've been looking through the memories and most of the tutorials were for Animation Shop. I did read some of the general Image Ready ones, but I just got myself completely confused. Could someone please direct me to a tutorial to make a mini movie icon using Image Ready?
I made a bunch of caps and I have a base, but have no idea how to animate my caps and put them into the base.

I've never done animation before, so any help/advice/suggestions would be really appreciated. Thank you!
