240 comes with a categories ... plugin or widget - I forget which, but it's there and it works.
On the permalinks thing: it might be because your server doesn't support "pretty" URLs. Of the top of my head I can't recall the wording, but on your Blog settings->pick a blog->URLs subtab there is always an option for "&this=that&foo=bar" type of URLs, and a couple of options for this/that/foo/bar type of URLs. Change yours to the first type and see if everything works again.
