Chroma Key in Motion?

[RC Ducantlin]

This is NOT spam. This is a ligitimate question. 

I am asking for something that should be intuative but eludes me.

Using video file with a Chroma Key area, I want to create a short video.  In the "green screen area" I want to insert JPG/PNGs of book covers. 

I can transform, skew, tilt, and resize the covers in PS.  I can insert background from the covers into the video using PS and PPro.

Q1: What I cannot do is move the JPG/PNG image to fit into the Chroma Key area. (Yes, I can create a backgound.) Is there a simple trick fill just the Chroma Key area?

Q2: Presuming I can fit the JPG/PNG cover image(s) correctly, how do I get it the inserted image to move in sync with the forground?

Q1-Select the background and go into effect controls to set the size and position where you'd like it to be.

Q2-In Premiere manually keyframe. After Effects has tools that would allow you to sync the motion of the background with the foreground.
