Kinda Confused

okay after doing flash for a lil bit im a bit confused… it seems like this stuff is mostly for graphics moving around and stuff like that. Now my question is… is it better off to make a site complete with flash or one that uses a header flash and the rest are html…And if i go with the header flash & rest HTML how do i connect the flash button menu so that it opens a page in my html. i dont know if i make any sense any help will be good thanks. I guess its kinda like kirupa site where the header is flash and the context is html…or maybe im wrong everything on kirupa site is flash hehe
