How to add additional category blocks to homepage?

[bboots]

I'm loving the Lifestyle theme and the excellent directions I've found here for modifying it. I used your recent tutorial for creating a widgeted footer and was surprised and pleased at how easy it was! Now I'd like to make a change to the main body of the blog home page and hoping it will be as do-able.

On the home page, under the featured content box, the body is divided into 3 columns of assigned categories. Two narrow columns sit over a third, wider column.

Is there a way I can repeat this, so that the arangement is two narrow, one wide, another two narrow and another wide column of categories on the homepage?
