Menu function not working with this theme

Question #1: I switched to the Blogs MU Theme here: I am trying to use the custom menu I’ve designated in the menu function under Appearance. While it says the theme supports 1 menu, it is not showing the menu I’ve designated. How do I rectify this?

Question #2: How do I get rid of the second row of service boxes on the bottom of the home page. I’d like to use 1 – 3 and delete 4 – 6. I’ve tried erasing the text and saving, but this doesn’t work.

Thank you in advance!
