I have decided to use Zbench as my theme for the my revised blog, for which I have a wiki article, called davelevy.info v4
See also WordPress themes at davelevy.info, which deals with the header.php, front pages, read more and category and tag lists.
The two initial problems I have are using the heading tags, and their code style.
I also would like to have the pages having individual comment closure dates, so that I can create an always open guest book, which i believe is possible on this wiki.
I need to check out Child Themes. This will make preserving customisations much easier.
