Now I want to remove the username & password section from this page and also I dont need "Authentication" from menu which is on the left side of the page. How can I handdle this scenario. Please give me full description realted to this scenario.

You need to edit customer/main/checkout.tpl. Try using webmaster mode, it will point you to the right templates.
