Help Choosing a Template: Suggestions, please.

Okay, I have my blog up and I’m posting to it regularly. Now, I want to start tidying up the look. I’m using Misty Look, now, but it’s not right for what I’d like to do.

I think a 3-column theme would be best. What I want to do is have the site specific stuff on the right and in the header bar. In the left-hand column, I’d like to put some ads. Not much, maybe just enough to get a little revenue to pay for the site.

Once the appearance of the site is set, I don’t want to fool with it much; I just want to focus on the writing.

What theme would work well with this approach? Should I do something different?

Thanks
