1)You can use css absolute positioning. What you'll want to do is to put
<div id="menu">THE MENU CODE</div>
then in the css:
#menu {
position: absolute;
left: Xpx;
top: Ypx;
}
where the X is the number of pixles from teh left of the page and the Y is the number of pixels from the top.
2)You'll need something like <a href="asdf.html" target="_self">woo</a> in your code. You can find more about it
