We present basic data and modeling for a survey of the cool, photo-ionizedCircum-Galactic Medium (CGM) of low-redshift galaxies using far-UV QSOabsorption line probes. This survey consists of "targeted" and "serendipitous"CGM subsamples, originally described in Stocke et al. (2013, Paper 1). Thetargeted subsample probes low-luminosity, late-type galaxies at $z<0.02$ withsmall impact parameters ($\langle\rho\rangle = 71$ kpc), and the serendipitoussubsample probes higher luminosity galaxies at $z\lesssim0.2$ with largerimpact parameters ($\langle\rho\rangle = 222$ kpc). HST and FUSE UVspectroscopy of the absorbers and basic data for the associated galaxies,derived from ground-based imaging and spectroscopy, are presented. We findbroad agreement with the COS-Halos results, but our sample shows no evidencefor changing ionization parameter or hydrogen density with distance from theCGM host galaxy, probably because the COS-Halos survey probes the CGM atsmaller impact parameters. We find at least two passive galaxies with H I andmetal-line absorption, confirming the intriguing COS-Halos result that galaxiessometimes have cool gas halos despite no on-going star formation. Using a newmethodology for fitting H I absorption complexes, we confirm the CGM cool gasmass of Paper 1, but this value is significantly smaller than found by theCOS-Halos survey. We trace much of this difference to the specific values ofthe low-$z$ meta-galactic ionization rate assumed. After accounting for thisdifference, a best-value for the CGM cool gas mass is found by combining theresults of both surveys to obtain $\log{(M/M_{\odot})}=10.5\pm0.3$, or ~30% ofthe total baryon reservoir of an $L \geq L^*$, star-forming galaxy.
