Help with Accordion -- Style Sheet Functions

Hello...Just download and integrated Accordion and it's working great.  However, I'm having trouble with some basic customization (obviously I'm not a programmer!).  Two things:  I'm trying to re-size the accordion without doing any coding, so I just selected everything in the design window of my HTML editor and did a right indent of 10 pts.  This worked great for what I needed.  Except, it did not indent the drop-down menu box -- text in box was indented, but not the box graphic.  How do I bring that box in?  Header boxes were indented, but not the drop-downs.
 
Also, how do I change the gray colors of the accordion boxes?  I did a search in the Forums and read about the ThemeRoller?  How does that integrate with the stylesheet? 
 
Thanks for any insight...
