We describe a SIRTF Legacy Science Program to carry out spectrophotometric observations of solar-type stars aimed at (1) defining the timescales over which terrestrial and gas giant planets are built, from measurements diagnostic of dust/gas masses and radial distributions; and (2) establishing the diversity of planetary architectures and the frequency of planetesimal collisions as a function of time through observations of circumstellar debris disks. Together, these observations will provide an astronomical context for understanding whether our solar system -- and its habitable planet -- is a common or a rare circumstance.

Here we summary properties of our sample, update the planned observing strategies, report the status of our ancillary observing programs, and describe modelling efforts aimed at interpreting complete spectral energy distributions from 0.3--1300 \mum.
