How to trim down a chunky MySQL database?

One of my blogs (http://www.clicksharpmarketing.com/blog/) has about 125 posts, and the MySQL database is taking up 96mb on the server. Seems to me that’s an abnormal sized footprint, no?

I’m aware of the plugins and hacks to disable autosave/revision tracking, which of course would have helped me in the past. But it seems there some major retroactive housecleaning in order… can anyone recommend a good plugin or some process I can use to trim all this fat out of my database?
