Columns of content on home page, by content type

Hi all, I’m using a template called “canvas” for a news website and want to be able to have two separate columns of most recent content on the home page. One column would feature all stories except these weekly reviews of business news I do, which are tagged as such, and another that only has the weekly reviews…I’d love to be able to do this without writing code, unless there is no easy way to do that or it will end up looking ugly. I want the 2nd column with weekly reviews to be skinner than the main column of stories. Can anyone help?
