We present an improved uvby-metallicity relation calibrated for F, G, and early K dwarfs and an analogous uvby-T_effrelation, both derived using a Levenberg-Marquardt minimization scheme. Our calibrations are based on 1533 stars that appear in both the Cayrel de Strobel metallicity compilation and in the Hauck-Mermilliod catalog of uvby photometry. We also examine the speculative possibility of using uvby photometry to produce a uvby-planeticity calibration. We conclude that while there is likely no strong photometric indicator of the presence or absence of short-period planets, the possibility of a spectroscopic indicator of planeticity is well worth examining.
