Unless you've changed the templates, the entry-title shouldn't be missing. If you have a look at the html on one of the pages on my theme demo, you'll see that it includes entry-title on the Post title.
The hCard author is included on blog pages, where it makes more sense to include the name of the person how wrote the post. If you want to display the name of the author on every single page, you're welcome to update the templates in your child theme.
Like most blogs, I've chosen to display the published date for the article, instead of the date the article was updated. Typically, most blog posts don't get updated frequently to warrant adding this extra date field. As I mentioned for the name above, it makes more sense to include this info on your blog posts, rather than pages. Since pages are typically static content, for things such as your "about" page, the date it was published and the author are less relevant.
