A couple of suggestions.  First, if I were trying this, I think I would 
control the distance to the vertices and the foci by sliders, and then 
compute the eccentricity from these so that as the shape changed, they would 
see that the eccentricity moved in relation.  This might require a separate 
sketch for hyperbola and ellipse.  

Suggestion two...  There is a dynamic geometry discussion group and the guys 
there are masters of working with these kinds of problems. Most of the Key 
Curriculum Press guys monitor this list, so send them your question. Usually 
what you get back are sample files. The URL for the discussion page is at 
http://mathforum.org/discussions/ . The dynamic geometry discussion list 
is toward the bottom left.

Good luck
