Answer 1

Did you specify your siteoforigin?
If the images can be found in the same project, try:
<Button>
<StackPanel Orientation="Horizontal">
<Image Source="pack://application:,,,/Resources/document-gear.png" Stretch="None" Margin="0,0,3,0" />
<TextBlock>Изменить настройки</TextBlock>
</StackPanel>
</Button>
So: pack://application:,,,/[path from root of project]
