Hi, sorry for the delay. From what I can see, you can solve your first question applying the following code in the Custom CSS Section of your Theme Options Panel.
.fourcol {padding-left: 2%; width: 28%}
.eightcol last {padding-right: 2%; width: 50%}
For the back ground color, you can use followin CSS code:
.post-52 {background-color: yurdesiredcolor}
With the exceprts, what you’ll need to do is go to your theme package, to the folder framework>functions and in the file post-functions.php look for line 396 and replace this code:
$output .= $excerpt_text;
with this code:
$output .= get_the_content();
Hope that works out for you!
