Use pacakges.ubuntu.com to find packages containing specific files.

We don't know - if the source is available, "Use the source Luke".

Probably a little better to symlink to /usr/lib/libexpat.so (which 
itself should be a symlink to the current version).

If you really have to have libexpat.so.0, you might try installing the 
package "wink", which just happens to include that file (bad packaging on 
the part of the maintainer, but you can take advantage of it).

You could also try downgrading to libexpat1 from gutsy or feisty (which 
both had this file) but I think that's likely to lead to major headaches 
with other apps needing the later libexpat.so
