Answer 1

I would say to use showModalDialog, so you will be freezing the parent window, and after it is done, you can send a variable to parent and do the redirect:

MainWindow:

function ShowModalForm()
{
    var urlToRedirect = window.showModalDialog('url');
    if (urlToRedirect) 
       window.location = urlToRedirect;
}

Popup Window:

function buttonAcceptClicked()
{
    //Do stuff you need
    window.returnValue = "new url";
    window.close()
}

Here is a lot of information about this.

From within the popup, you can use the opener property to reference the parent window...

opener.location.href = 'http://www.google.com';

You can also invoke functions on the parent window...

opener.functionName();

Of course, the good old same origin policy restrictions apply here
