I am looking to change the look and feel of the home page

I am looking to change the look and feel of the home page layout for the wiki pro. I am looking for something similar to the following: http://www.classifiedads.com/

I don't want to change the look and feel of the actual wiki pages. I just want the home page to have a 3 column layout (2 columns wiki and 1 column sidebar) so that everything looks nice and neat for a user when visiting the page.

So:
1) Wiki layout change on home page
2) Wiki laid out by name
3) Sub-Wiki linked under main wiki name
