Animation constraints for toy JCB

Croftyness

At the moment I have the white base of the eyes on a "look at constraint".
Is there any way I can get the pupils to move in a similar way, but locked onto the face of the eyes?

Also at the moment I have tracks that I plan animate by changing the percentage value of the path constraint, and animating the wheels after.
Is there any easier way to do this so they all move together with a single slider?

I would just use wire parameters. I made an example file:

This could be a problem. The way tracked vehicles work they are independent of each other. To turn they spin opposite of each other.
