Answer 1

I'm surprised that HTML works as expected anywhere, but then IE7 is a large pile of bugs.
You have a <ul> as a child of another <ul>, which isn't valid HTML. <ul> can only contain <li> elements. That sub-menu list should be the child of the <li> above it:
<li class='has-sub'><a href='#'><span>text</span></a>
<ul>
<li><a href='url'><span>text</span></a></li>
<li><a href='url'><span>text</span></a></li>
</ul>
</li>
