How to add right arrow image to wpf tabitem when it is selected and style like left nav

I have looked around on stackoverflow and the internet but haven't found an answer for a specific problem. I want to create a TabControl/TabItem combination that acts like a left nav. I am still new to XAML (only using it for a few months now) and I cannot figure out the best way to accomplish this. I also want to add a small arrow icon to the currently selected tab header. In the end I would like it to look similar to the design shown in dnrtv episode 115 featuring Billy Hollis' great design, he mentions that this is a TabControl that has been styled to look like it does. Check out this link and go to 4:43 to see what I mean: dnrtv Billy Hollis

So far I have been able to get this far from searching for almost a whole day online:

<TabItem Header="Tab1Header"/>
<TabItem Header="Tab2Header" />
<TabItem Header="Tab3Header" /> 

</TabControl>

This code gets me the headers on the left and some look but I need to figure how to add the icon when a TabItem's IsSelected property is true. Also, I'd like to eliminate the borders if at all possible. Please let me know if I am barking up the wrong tree and need to style it differently.

Should I use a DataTemplateSelector or so开发者_StackOverflow社区mething like that? I'd like to do it in all xaml but if that is not possible than that's okay.

Any help would be greatly appreciated!

Here is one that I modeled after that one with a few changes maybe 6 months ago:
