How to delete blog related coding using a Theme

Hello all! I’m new to WordPress. I’m setting up a new website for a client and have chosen the State of Mind theme. I need to get rid of all the Blog elements of the theme since it’s meant to be a dental office website. One of the most important changes will be getting rid of the time stamped entry feature that is key to blogs. Is this a matter of going into Appearance -> Editor -> and deleting some code? If so, which code? Are there any widgets that would be a smoother solution?

Also, how do I get rid of blog related links that come up by default on the Home Page?

thanks
