Welcome to the Q&A Forum

I am not sure why you are setting disallow of file types.  Google would not index wmv or js etc anyway as it cannot parse that type of file for data. If you want to coax  google into indexing your site submit a sitemap in webmaster tools. You could also set NoFollow on the anchors for the pages you want to exclude and keep robots.txt cleaner by just including top  level subdirectories such as admin etc. There just seems to be a lot of directories in there that do not relate to actual pages, and google is only concerned with renderable pages.
