Unwanted: space in blog summary/excerpt & line in image caption

Hi, Catch Box looks great! The layout is very pleasing and it's really easy to work with. Nice tidy code too. However, I've run into 2 annoying things that I can't find a resolution for. See http://pamelacross.ca: 1) I've set up the homepage to show blog excerpts. Under the excerpt, before links about tags, author and category, there's a big space. How do I get rid of this? 2) When I use a caption on an image, there's an annoying little line that appears in the caption under some of the text. Help on this greatly appreciated! -pjw
