It looks like gggreg has already fixed the font problem by changing themes on his blog. The side bar's on the left now and the links there are perfectly readable.
Boogie, I'm no coder so all I can do is suggest something to try. The style sheet you're using now appears to be:

If you open that in a text editor and do a search and replace, replacing all instances of lucida grande with something common like times new roman, it might fix the problem. Be sure and save a copy of the original style.css in case the change screws things up.
