Problem solved, a fellow Plogger user sent me the following instructions:
The lines are actually borders set in the css file for the breadcrumbs and footer (aka pagination) section. Here is the section from my css in which you can see I've commented out the sections that add the border-top and border-bottom for the pagination section and I've commented everything having to do with borders in the breadcrumbs section. Making the same modifications to your css file (gallery.css) should achieve the results you're after!!
The rss link is created in the gallery.php file way down in the the_gallery() method. I've copied the relevant section from my gallery.php file so you can see the changes I made. The changes are indicated by // BEC comments. I basically just prevented it from writing out the rss tag line by commenting this line: <!--<td style="text-align: right; white-space: nowrap;">'.$rss_tag.'</td>-->
