I ran across the same problem and after a lot of research and frustration I finally resorted to using the PRE tag as a container for VB code. The PRE tag preserves all line spacing and basically allows a WYSIWYG look. It’s not perfect – for example, I would like to show comments in green just like the Excel VB editor does but I’ve not yet been able to figure out how to allow changes in font coloring to appear within the PRE container. Then, there’s possibly the indentation problem that you experienced when using my RSS feed – I’m still not sure what is happening there and if the PRE tag could somehow be the cause. However, in all other respects the PRE tag does the job well and also helps to keep the site compliant to XHTML standards. You can also apply formatting via your CSS template to the PRE tag. That’s how I’m adding the gray boxed look to all of my coding examples.

Some resources for the PRE tag and general design if you’re interested:

By the way, I really like the format of your site – it looks great and the content, as always, is very interesting. I read it every day.
