You should be able to design good lessons directly based on the book sections. As long as you use a Pre-Calculus book you will have rich enough information available.

Be sure to demonstrate the conic sections using a realistic three-dimensional model. Also use the definitions of each conic section and the distance formula to derive the equation for each conic section, and include the analytical cartesian graph for each.

You are right on-target about not just giving a bunch of formulas. The demonstration and the derivations are important for learning and understanding.
