The COMPLETE (COordinated Molecular Probe Line Extinction Thermal Emission) Survey has extensively mapped the star formation regions of Perseus, Ophiuchus, and Serpens, complementing observations from the Spitzer c2d Legacy Survey. "Phase I" data, comprising of wide-field maps, is published and publicly available. More detailed observations, which are part of "Phase II," have been completed. Combined with other observations, we investigate the star forming regions in detail, as well as the limitations intrinsic to observations. Using IRAS and Spitzer/MIPS FIR emission maps, we have created dust temperature and column density maps of the Perseus Molecular Cloud. We have obtained ammonia spectra using the GBT of every millimeter-bright dense core in Perseus, allowing studies of core kinematics, dynamics, chemical evolution and temperature using a data set of unparalleled uniformity. By considering whether cores are associated with young protostars or are inside cluster regions we identify which physical properties (e.g. temperature and chemistry) are influenced strongly by internal star formation, and which are influenced by cluster environment. Through the large scale 12CO and 13CO maps of Perseus, we find that the standard X- factor to convert 12CO integrated intensity into H2 column density is strongly affected by saturated emission above 4 mag, and therefore overestimates this conversion factor by a factor of a few. We find that the 13CO abundance agrees with previous determinations, but the extinction needed for self-shielding is larger by 1 mag. 3D visualization is used to analyze many cloud properties. Potential outflow sources as well extensions from previously known ones are identified. Visualization is also used to identify coherent features from channel maps. We also apply radiative transfer to simulations of star forming regions, in order to further understand derived properties such as column density and temperature from observations.
