I’ve been doing working on a similar thing this evening.
I’ve found 2 applications that can take an rss feed and post it to your facebook pages wall. These are ‘Notes and ‘Social RSS‘.
Notes allows you to add 1 rss feed to your wall and publish it with links. Social RSS allows you to add up to 5 rss feeds and also gives you more scope for customisation. Wether it will do the $category | $post_title, I don’t know.
To exclude categories use a custom rss feed which excludes the categories you do not want to publish. An article on how to do this can be found here:

Hope that helps.
