We review the progress of the N2K project, which has recently measured the atmospheric parameters of 1907 stars as part of a mission to find the "Next Two Thousand" metal-rich targets for the Keck/Subaru/Magellan planet search. We also discuss the optimal target selection procedure for extrasolar planet searches, and compare methods of estimating [Fe/H] from photometry and low-resolution spectroscopy. Finally, we report the discovery of 3 new planets from the N2K pool of targets, and estimate the number of planets that will be detected around N2K's 431 stars with [Fe/H] > 0.2 at the end of a four-year observational baseline.Based on observations conducted at the KPNO 2.1m telescope. This work was supported by the NSF Graduate Research Fellowship awarded to S. R., S. A., and J. S. Additional support was provided by the NASA Origins of Solar System Program through a grant to G. L.
