Astrocycles Adding custom sidebar Wordpress

I have a site [login to view URL] which is 4 gig. It was all in the Main theme and not the child theme. Each time I upload an image it makes like 20 images. I Installed the latest theme and exported this site to [login to view URL] in the Child theme. Instead of having WP make folders for each month, I put all the images in the uploads folder directly and edited the links so we have only one folder to optimize. Now the site is only 400megs. Only the banners for each page we are using the Media within WP. Here are the tasks to do immediately: 1- We need a sidebar for all pages just like astrocycles.net. I have already put this in [login to view URL] but it is not showing up. We don't want the home page to have any sidebars. 2- when we add new images using Media I want it to directly go to the uploads folder unless this would affect future updates. This is just a small test to see the abilities.
