Link for Category to Page

Ummm, I hope I’m not missing something, but the footer on this site says that the site is powered by Drupal, not WordPress. I’d really like to help you, but I don’t know Drupal at all. (This is a WordPress forum…)

Ok, thanks for the link. That does make more sense. 😉 (Much better looking site, too!)
I’m not completely understanding your first question, though. I don’t think by “category” you mean the same thing as a “category” in WP lingo: a collection of related posts.
Right now, you have info about the Men’s Ministry on the Men’s Ministry page, and you want to add Events, right? I see you’re using a Google Calendar Events plugin. Is there some issue with it posting events on that page? (I have absolutely no familiarity with that plugin. Maybe this is a question for the plugin’s forum?)

I think in your second question you’re saying that you want a sidebar that only appears on the About page, right? If I’m understanding this correctly, you could create a template to use for your About page, and create a static sidebar for that page.

I’m not familiar with the theme you’re using, and I don’t see that it contains any “sidebars” in WP terminology, but the template you’re using for the Media, Events, and apparently the 404 (page not found or 404.php) page have a div which is appearing on the right. You could find the .php file that is being used for those pages, copy it, change the name, then put the links you want into the <div id=”navigation”> </div> section.
If you look at the edit screen for one of those pages, the field labeled ‘Template’ will tell you the name of the template being used for those pages.
Then, click Appearance -> Editor to see a list of the files in your site, and figure out which php file that template is, copy it, change the name, and put your links in the navigation div. (You’ll need to edit the file after you copy it to change the template name in the file. It will probably the second or third line of the template file.)
