I'm afraid you'll probably need to break the line up on your own, or
using an external tool. A simple regex should break it up for you
though. :s#[{};]#\0\r#g should be a good start for valid CSS code.
Then you can visually select the entire area of interest and hit = to
apply the filetype indent rule if you've enabled that feature. That
should do a fairly decent job of cleaning things up.

For the *highlighting*, see our current featured tip at the wiki:
http://vim.wikia.com/wiki/Different_syntax_highlighting_within_regions_of_a_file
Many syntax files actually do this already.
For indentation, you can modify the indent script, perhaps something
like what is contained near the bottom here:
