How do I create new page?

Can someone give a quick rundown (or link to) making a seperate page in the WP layout? In other words, I want to create newpage.php that will have outlines for books that I have written and so forth….I want it to look just like the other pages so could I essentially remove the <content> part from the index.php and replace it with my new page and then rename/save/upload/ and link to it? If it is that is, just another reason I’m infatuated with WP….Thanks in advance, and Ciao!
