sidebars are called by a small piece of php code
it should say get sidebar
you need to move that code from the footer file to another file
honestly your requests are pretty time consuming to explain in a support post and are basic wordpress theme questions.
You might want to go to your Appearance Menu
See if you have an empty widget area setup for your old sidebar .. sidebars don’t usually show if the widget is not populated with something so drag a text or search into it and see if you can see the sidebar in the location you want.
see if you have the option to enable disable sidebars
if not then you are in for some theme editing
please post in your theme’s support section at http://wordpress.org/support/theme/the-night-watch/#postform
you might need to provide a live link to your site.
