There probably is a page or web site that has all the locations for the various Poser-related files, but I suspect you'll learn like the rest of us - diggin' around in the Poser directory (folder) and subdirectories using either My Computer or Windows Explorer. By the way, if a zipped file has both an .OBJ file and texture files (usually .JPG or .TIF), put the texture files in the same folder that the .OBJ file goes in. That way, the textures load automatically. Took me a year to discover that one!
