Answer 1

When you're using a Repeater to build up lists, it's generally easier to put the <ul> opening and closing tags in the repeater's header and footer, respectively. So something like this:
<asp:Repeater ... runat="server">
<HeaderTemplate>
<ul>
</HeaderTemplate>
<ItemTemplate>
<li><!-- data binding stuff --></li>
</ItemTemplate>
<FooterTemplate>
</ul>
</FooterTemplate>
</asp:Repeater>

Answer 2

Nevermind, there was a missing close tag in FooterTemplate /FooterTemplate
