I looked at this when you first posted and you were working on it so I came back to it before I went to bed and it was all working correctly – now it’s not, of course.
There is something that is causing your css and js directory paths to be incorrect. Your files are there but it’s getting confused about where “there” is.
I know it’s frustrating (I’d be frustrated at any rate) but maybe go back and disable all plugins and then make sure you’ve cleared your browser’s cache completely using eg Chrome->Tools->Clear browsing data to test.
