Create a Wordpress Template

I have a Wordpress site based on a Coraline theme. [login to view URL] I need to MODIFY one static page on the site that has custom sidebar content just for that page (different from default sidebars on the homepage and the other standard pages throughout the site). [login to view URL] You need to: 1) Make a new theme template (Call it "2_COL_R_SIDEBAR") that is: 2 columns (body content on the left and CUSTOM right sidebar on the right) 2) Right Sidebar column should be the same width as in the current setup. 3) This page's Right sidebar should be different than the Right sidebar on other pages on the site. 4) It should have placeholders for custom widgets that I can edit from regular WP widget editor. 5) Everything else on the site should stay the same - no other pages should be changed - no other content should be changed. This is very important.
