Is this possible?

Im sorry if this is an obvious answer but lately Ive been retarded and missing the obvious.

I was thinking of using the showcase theme to show the features of my site... it wont however be a site that needs a portfolio so Im trying to remove that option from the menu... the top menu is easy, but is there a way to mess with the menu that is in the footer, or even remove that menu?

Also the posts below the rotating pictures... Ill want 3 links down there and the current look would work great, but is there a way to keep the same visible posts, or better yet pages? That way I can have a news section or whatever and be able to add to it without screwing up my main front page.

The other option would be figuring a theme out like the inuit one... http://www.intuit.com/website-building-software/ which would take me awhile since as I said Im retarded lately lol
