Numerous Questions

Hi, We have the Clean Journal Pro theme and we have encountered a few items when trying to customize our theme and were hoping someone could assist. We're trying to center our 'Most Recent Blog Posts' but cannot find the code. Currently it's left-aligned. Is there a way to add a font from FontSquirrel easily to this theme? Can we change the hover color for social icons? Can we remove the search bar that's in the header? I can find where to add and remove it in the navigation but not in the header area. Can we remove the link for the author? We don't want our author to have a link/page. Thank you for your assistance!
