Entries: I couldn't find coding that would disallow text to wrap around the user icon. (It's my one pet peeve about the Expressive layout.) I found coding that positioned the text under the user icon, but that wasn't really what I was looking for.
Sidebar: I'd like to get rid of the calender and page summary. I found this post, but it's dealing with someone who used pre-existing custom text that I don't have.
Like I said, I've spent awhile going through the tags, and I'm fairly certain I couldn't find the solutions I'm looking for. If they are there, I'd love to be pointed in the right direction.
Here are the theme layer and style preview.
