You've decided to go with HTML navigation. This is probably the best thing to do because your Web site will follow the general example set by other (big) Web sites. (That is, people are used to the "template," and it is just much easier to navigate through than Web sites that use other navigation techniques.) When you are using HTML for navigation, I advise you to have a navigation bar, either on the top or top-left side of the screen, which is visible at all times. In this bar (or somewhere around it), you should always include these:

Site maps are not seen on that many Web sites yet, but I highly recommend that you add one to the site you're designing. It makes it a whole lot easier for disoriented visitors to find their way around the site when they are lost. An image map is an "index" of all the sections and pages that the Web site contains. For an example, click here.
Here again, you have the choice of button or text links. Be sure to keep a consistent pattern throughout the site; don't change the location of the nav-bar (if you have one), or switch from text links to buttons. Be a good host. Rather than just providing them with links, guide them along the pages, explaining them where they can go and what they can do from their current position.
