A script that will export out just model, texture and material information

I am looking for a script that will export out scene information relating to....

Object name + poly count of object
Materials associated with object and the material types
Textures associated with materials of that object
Texture names & sizes

and then I hope to add the information to an Excel file. It seems easy enough, but I don't have much time and can't seem to find a script online. The data under File/SummaryInfo helps, and exporting an ASCII file is good, but I it requires too much time going through numerous objects. Any help would be appreciated. :)
