How to change comment style "look" - it seems to have changed itself

Okay, I may have solved this issue by turning off some of the Spam Free WP features. However if you still look at my site could you tell me if you know how to get the comments to be numbered? That's a feature I would love to have and see that some sites do have.

I have used Atahualpa for years and love it. However I just noticed that in the last few weeks (maybe even days) our comments now show up as "quotes" (they look like comment bubbles) instead of the list look that I had before. The site is http://www.milehighonthecheap.com and you can see this on any post that shows it has a comment. The system also doesn't seem to recognize me as the admin anymore in that it doesn't change the color of my comments to the pinkish background).

I am also using Spam Free Wordpress as we were getting hammered with spam and also in last month moved to a dedicated server. Any guess as to the issue? I'd really like the old Atahualpa list "look" back as when I get hundreds of comments (say for a contest) all those strange bubbles are going to make it hard to read and navigate. Also is there a way to get the theme to auto-number comments.

Thanks for any help.
