Category Blog Page – How not to display the new category in the sidebar

[Tanya]

Hello!

I want to create a new page on my blog (I'm using Genesis Balance child theme) with a new category (it will be new topic actually - different from those what I normally write on my blog about) using Category Blog Page (http://my.studiopress.com/tutorials/category-blog-page/). I don't want to display this new category in the blog sidebar. How could I do this (hide this new category from the sidebar)?

And here is the second question about Category Blog Page. How can I pin (lock) one post (it's gonna be kinda main post, the biggest one) so that it would be always on the top of the page (even the newest posts must go down, below this main post) and make it in full (not excerpt)?

Thank you in advance.

And I also forgot to add that I don't want these new posts to be displayed in the blog (among the other blog posts).
Generally, I want to create a blog page which would be like a separate small blog (where I will write posts on the subject which is totally different from the blog's subjects).
The main post will be locked (pinned) on top and the rest of the posts will be under it like small updates(news) on the same subject.
