Hi,
I think if you go to the page settings for the home page (ie click the top right gears) and uncheck "Show Child Pages Index" that will get rid of it. However it seems to be showing more than just child pages so I suspect something got boogered up in your layout.master file but not sure what it is. You might compare your customized one very closely with the original tabular1 skin and find some setting is different.
Hope it helps,
Jooe
