Problems after upgrade

Thanks in advance to any and all help with this problem my friend is having with his WP-powered site — http://www.steelcityhobbies.com. I upgraded it to 2.2 last evening and see two problems that I don’t know how to fix:

1. The “Link” section has now lost all formatting and the bullet points that could come with
# definitions. I’ve used the following code for the Links section:

<?php wp_list_bookmarks(‘categorize=0&title_li=’); ?>

I’d appreciate it if someone could please explain what I can do to fix this.

2. Archives — As you’ll see, there’s now a “0” entry under the archives on the home page — and I have NO idea where it came from. Again, any help/advice to fix this is greatly appreciated.
