Toggle features such as title in pages, menus, ect

How can I toggle items on the pages. For instance I already had a menu bar in joomla with OS Property now I have 2 menu bars. I also don't want agents to be able to register. I have a menu bar on the home page that says "back My details Compare properties" I don't need that to show up at all. When I go to my home page Home on my menu is highlighted and I don't like the Title "Home" on that page nor do I like the title to be on any page. When I try to use the search feature I always have to chose a state. I live in Kansas and I am not selling or renting homes outside of Kansas therefore I would like that as the default selection. The demo site looks nice yet after the install into my website there seems to be too much unwanted features that I can't find a toggle for.
