Answer 1

Try this
use this name space using System.Windows.Media; and in button click event write this
private void WhereToStayButton_Click(object sender, RoutedEventArgs e)
{
stackpanelname.Background = new SolidColorBrush(Colors.Red);
}

You can do that by applying Storyboard on Click event trigger:
<ControlTemplate TargetType="HyperlinkButton">
<StackPanel Orientation="Horizontal" Background="#EBEBEB" x:Name="sp1">
<Image Source="/Assets/Menu/wheretostay.png" Stretch="None"/>
<TextBlock />
</StackPanel>
<ControlTemplate.Triggers>
<EventTrigger RoutedEvent="ButtonBase.Click">
<BeginStoryboard>
<Storyboard>
<ColorAnimation To="Green" Storyboard.TargetName="sp1"
Storyboard.TargetProperty="Background.Color"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</ControlTemplate.Triggers>
</ControlTemplate>
For Windows Phone 7, use Visual State:
<ControlTemplate TargetType="HyperlinkButton">
<ControlTemplate.Resources>
<SolidColorBrush x:Key="PhoneBackgrounBrush" Color="Green"/>
</ControlTemplate.Resources>
<StackPanel Orientation="Horizontal" x:Name="sp1">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed">
<Storyboard>
<ObjectAnimationUsingKeyFrames
Storyboard.TargetProperty="Background"
Storyboard.TargetName="sp1">
<DiscreteObjectKeyFrame KeyTime="0"
Value="{StaticResource PhoneBackgrounBrush}"/>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Image Source="/Assets/Menu/wheretostay.png" Stretch="None"/>
<TextBlock />
</StackPanel>
</ControlTemplate>

As Rohit said, Make use of Visual states to achive your requirement..,
<ControlTemplate TargetType="HyperlinkButton">
<StackPanel Orientation="Horizontal" Background="#EBEBEB" x:Name="sp1">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="CommonStates">
<VisualState x:Name="Normal"/>
<VisualState x:Name="MouseOver"/>
<VisualState x:Name="Pressed">
<Storyboard>
<ColorAnimationUsingKeyFrames Storyboard.TargetProperty="(Panel.Background).(SolidColorBrush.Color)" Storyboard.TargetName="sp1">
<EasingColorKeyFrame KeyTime="0" Value="#FFE91818"/>
</ColorAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="Disabled"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Image Source="/Assets/Menu/wheretostay.png" Stretch="None"/>
<TextBlock />
</StackPanel>
</ControlTemplate>
