Problem with Delicacy Theme 1.2.4

I’m having a problem with the Delicacy theme. Putting text into italics does not work for me. Also, if I am putting something in quotations, it will show the open quotation as an apostrophe, and the closing quotation as a regular quotation. (i.e. “this” becomes ‘this”).

Also, I was wondering if there is any way to adjust the main content font size and expand the sidebar by a couple of pixels? Most of my ads and widgets are 300px wide, and the sidebar cuts off the end.

Thank you!
