@mstaudt131: for search box in the header border, you can just add the following CSS in “Custom CSS” box in your Theme Option panel.
#branding .searchform .search-box { border: 1px solid #000; line-height: 33px; }
But for adding blogspot icon in the social icon list. This is bit complicated. First you need to add icon in this image social-profile.png and then build child theme. Where you need to remove the current social icon function
remove_action( 'simplecatch_sidebartop', 'simplecatch_headersocialnetworks', 10 );
and then add your action for the function and edit the css. If you are not a developer then I recommend to hire developer for this or use tweaky services.
