Few customisations??

I am using Foodmania Free Theme on a demo site for teaching WordPress. I created a page called "blog" but because there is no blog template to assign, I went into the Reading Settings and set it to static pages. I didn't specify a page for the homepage but then set the "blog" page to display posts. This achieves what I want for the blog page but now the blog page and the homepage show ARCHIVE as a heading layered over the Header Image. How can I get rid of the ARCHIVE headings? It is assigned "entry-title" in CSS but if I set the display to none then I also lose all the post headings etc which I want. Any suggestions?
