Newbie Needs Help

I just started using wordpress and love it. I downloaded and installed the latest version, but would like to do more with it. I see we can add other pages to the blog, but we always have to go to that page and edit the information. I am trying to have a page where it is dedciated to manufactures and then below that has sony, hitachi etc. Is there an add on for this or can a page only be just one page? Aslo I would like to use droop down menus so when someone hovers over a page, it will drop down a menu and then they can pick from that.

Thanks
