I am CSS trapped again!

I thought I had settled my problems with proper display of this blog when I used a new template when Blogger had a major update. I found one minor problem with the template right away, but now a reader pointed out another, more significant problem. If I ever feel that CSS can be reliable, I will change my company's website away from tables.

Minor problem: Upon applying a format change, such as a bullet list, the font size becomes larger, and remains large throughout the rest of the post. Scroll down to see a sample. Of course, Blogger's demo of the template I am using, Thisaway, doesn't have this problem.

Major problem: With IE6 browsers, the right hand 'about me' column gets pushed down to the bottom of the page. I don't know when this happened, but assumed it was a recent change caused by the pictures I posted of my summer reading list. I deleted all pictures from my posts.

As an avid user of Firefox, I hadn't seen this second problem (thanks Brian), but since a lot of my visitors from Google are IE6 users, I want to make sure I have a proper introduction.

Since the creator of the template doesn't seem interested in answering questions, I thought I might ask my more geeky readers for advice.
