Navigation Buttons

Hello All,

I am brand new to wordpress and am just trying to set up an online book store.
I am having difficulty setting up naviation buttons to my main pages.
Home page has come up automatically, but I would like to set up a few more page links next to it.

I was also wondering if anyone knew any good tutorials to setting up an online store.

Any constructive assistance would be great
