I was not sure if i had to do it this way or not and need expert advice.

Typically, i am use to doing sprites when each image has the same dimensions. However, each image in the nav is not the same size. So i achieved it with the code below (header HTML & CSS).

I wanted to know if i have redundancies and if there was a shorter, more concise way to do this. Thanks!
#header-nav{
	float:left; /*left*/

	margin-left:20px;

	float:left;
	margin-left:10px;

	display:block;
	height:30px;

When it comes to sprites it looks like you have everything the way it needs to be.  Your only calling your background image once and only setting your background position against hovers.  

Overall it looks good

Ok. Thanks. Sprites are awesome! I'm not sure if it is because i haven't slept in 72 hrs... but i don't know if these 4 calls have redendency...
  1. In group A do i need to have dispay on group B as well?
  2. In group B - do i need to keep all in bold, they seem duplicitive with A and D (display:none)
    1. Doesn't text-indent:-9999px do the same thing as group D?
  3. It seems a lot of the tutorials on sprites that i have seen don't use the postion att. and the position att. for hover. I have only seen them use it for hover.
  4. Do i need all these dispay:block?
/*GROUP A*/
#header-nav li{  
        display:block;  
        float:left;  
        margin-left:10px;  
}  

/*GROUP B*/
#header-nav li a{  
        display:block;  
       height:30px;  
       text-indent:-9999px;  
        width:85px;  
}

/*GROUP C*/
#nav-about,  
#nav-runway,  
#nav-press,  
#nav-social,  
#nav-music,  
#nav-stockist,  
#nav-contact-us{  
        background:url(/assets/images/nav/header-nav.gif) no-repeat 0 0;  
        display:block;  
        float:left;  
        height:30px;  
        width:85px;  

/*GROUP D*/
#nav-about span,  
#nav-runway span,  
#nav-press span,  
#nav-social span,  
#nav-music span,  
#nav-stockist span,  
#nav-contact-us span{  
        display:none;  
}
Thanks!

  1. In group A do i need to have display on group B as well?
     - Yes, because Group A is specifying the container of the <a> tag and Group B is the <a> tag.
  2. In group B - do i need to keep all in bold, they seem duplicitive with A and D (display:none) - Theoretically you could remove the text-indent from Group B, but again your specifying a completely different element.  
  3. Doesn't text-indent:-9999px do the same thing as group D?  - Again, different elements
  4. It  seems a lot of the tutorials on sprites that i have seen don't use the  postion att. and the position att. for hover. I have only seen them use  it for hover.  - Not sure what you mean here.  If your talking about your background position, then you do have it correct.  I wouldn't have done it any other way.
  5. Do i need all these dispay:block? -  Yes, because the li's are inline elements and if you do not specify display:block, then you'll have trouble with your linking and more than likely layout of the nav.  
If you had a working page or a live link, I could tell you a lot more.  Like I said though, everything seems to be in order with no major duplication or useless code.
