I would suggest you to use our Implicit Styles. More information about them can be found in this help article.
You can find the style locally, where the Telerik Ui for Silverlight is installed, inside the Themes.Implicit folder. The full path would be:
C:\Program Files (x86)\Telerik\UI for Silverlight Q1 2014\Themes.Implicit\OfficeBlack\Themes\Telerik.Windows.Controls.GridView.xaml. You can then copy the template for the GroupHeaderRow and change it per your requirements.

By process of elimination I realized that the cause is that much of my restyling involves changing the backgrounds to, unfortunately this leads to the group headers being displayed underneath the various other items (rows/footers) etc. when scrolling. Is there any way to solve this without setting explicit backgrounds? (P.S. I'm using RadControls for Silverlight Q3 2012 if it has any significance).
I could hardly guess what may be the problem since the information you provided is not enough. Generally, you should not have any problems if you are using the default template of GroupHeaderRow. I suppose that the problem is caused by the modification you made to the GroupHeaderRow's template. I can suggest that you compare your modified template with the default one and check if you have removed some important "parts" of the template.
