You are right the '5' represents the layer ID.
The mouse over and mouse click events to produce maptips are managed by the maptip widget, so you don't have to worry about that.
After changing the Url, do you get some features displayed in your graphic layer?

Thanks dbroux. Actually I don't. After looking at it some more I decided to try a little different approach and instead of replacing the URL I just added another layer with appropriate changes. The new layer should show school districts somewhat analogous to the states but it shows nothing. My xaml and code behind is below.<esri:GraphicsLayer ID="SchoolsGraphicsLayer" Initialized="SchoolsGraphicsLayer_Initialized" >
<esri:GraphicsLayer.MapTip>
<Border esri:GraphicsLayer.MapTipHideDelay="00:00:01.5" CornerRadius="10" BorderBrush="#FF222957" BorderThickness="3" Margin="0,0,15,15">
<Border.Background>
<LinearGradientBrush EndPoint="1.038,1.136" StartPoint="0.015,0.188">
<GradientStop Color="#FFD1DFF2"/>
<GradientStop Color="#FF092959" Offset="0.946"/>
</LinearGradientBrush>
</Border.Background>
<Border.Effect>
<DropShadowEffect ShadowDepth="10" BlurRadius="14" Direction="300" />
