Answer 1

none of your windows have a URL to tell Ti where to get the js file
Ti.UI.createWindow({
url: 'link/to/js/file.js',
title: 'Window Title',
backgroundColor: '#fff'
});
each of your windows defined need to have a URL if you are going to link to them by added them to a tab like so window: win1
as for the icon no showing up the image path is probably incorrect.
