Our blog URL I want to specify. Example - http://www.ourblog.com/ourblog.htm do not want to default URL. Please tell me how this kind of URL can add to our blog.
You can change individual page and post links via the Permalink: area beneather the wordpress post/page title. You can also set up and alter the link in the Settings > Permalinks part of the online admin area. You probably need to select custom structure and add /%postname%/ Code (markup): into the settings box. This combined with the Permalink editing on the post should sort you out. It will be .php rather than .htm as this is how wordpress works.
