Posting info to display seperatly

Basically what I am wanting to do is when I post in a seperate category it will not be displayed with the other categories on the front page but rather then a seperate section on the front page. For example.

I have categories News, Events, Reviews.

When I post in news and events it will be displayed in one section of the site on the front page. But when I post in reviews it will be displayed in another spot on the front page. Any help on this would be great! Also I need to make my main news section ignore the reviews category so that when I post in the reviews cat it wont double post in both places on the front page.
