post obstructing right sidebar

Hello –
I’ve been tinkering with this site for a few days and have run into a situation where I have created page templates to display categorized posts on a number of pages. The problem I am having now is that the posts are running through the right sidebar. I would like to keep the sidebar rather than a work around of making a new full width php file w/ cat search code inside of it. Any help would be appreciated.
