I've not played much with WP7 ToolKit but I've managed to display list like this:

In XAML - removed Grid and added isFlatList:

<toolkit:LongListSelector Name="MyLLS" IsFlatList="True">
    <toolkit:LongListSelector.ItemTemplate>
        <DataTemplate>
              <TextBlock Text="{Binding Title}"/>
        </DataTemplate>
    </toolkit:LongListSelector.ItemTemplate>
</toolkit:LongListSelector>

In code behind:

ObservableCollection<NewsItem> myList = new ObservableCollection<NewsItem>();

MainPage()
{
    InitializeComponent();
    // something already
    MyLLS.ItemsSource = myList;
    myList.Add(new NewsItem { Link = "http://google.com", Title= "Google Search" });
}

I haven't got much time to play with the code above, but maybe it will help. I would advise to read some tutorials - WP7 LongListSelector in depth Part1, WP7 LongListSelector in depth Part2 and probably more.
