Pages and Templates

I would appreciate some help.
I created a landing page and it is attached to the landing page template and it works. Then I created a HOME page that is based on the Home template and in the menu I created the HOME button that appears as a button in the navigation. BUT, When I click it I get the url as: http://howyoustopforeclosure.com/home/ and Page Not Found. How can I make it found.
2nd problem. I created a BLOG page and attached it to Default Template.
BUT what show up when clicking the BLOG button is the HOME page. HOW can I get the blog page to look like a blog page? I don’t know if the Default Template has been changed to the Home Template. I can’t find any Default Template in the files, but is shows up under templates.
Thanks for any help, Arne
