I couldnt understand much of your wishes but as far as I understand I will tell you how to do it.
image caption:
open your rotation_headlines_list_v_2.css file in your theme folder and customize the image caption part.
mine is like this:
Code:
.headline_image div.image_caption {
position: absolute;
bottom: 0;
left: 0px;
width: 400px;
text-align: left;
font-size: 12px;
color: #FFFFFF;
background-color: #000000;
padding: 6px;
z-index: 999;
opacity: .70; /* Standard style for transparency */
-moz-opacity: .70; /* Transparency for older Mozillas */
filter: alpha(opacity=70); /* Transparency for IE */
