After you have the user registration you have to define the way you build up the URL based on the users account.
One way could be that after successful login you redirect to the target page e.g. in ASP this looks like this:
<% response.redirect("http://www.xyz.com/user.html?username=name") %>
On the target page you can use the username to build up the user specific items.
Another way could be that you set a session variable with the username and on the next page you use this session variable to build the custom site. Remember session variables in IIS uses cookies.
The login tutorials from 4guysfromrolla and the pages at msdn cover the redirect to user-specific pages etc.. Additionally the following articles are helpful in creating customised pages:http://www.4guysfromrolla.com/webtech/050199-1.shtml
and this one

I hope this helps, give me shout if I can assist you building this page
