Building a web site isn't something that is really cut and dry. There's a huge variety of products and services that can either help you get your web site where you want it or simply confuse you. It's also important that you make the right choices upfront so that you don't end up having to restructure your whole web site because of some problem in your design layout. The level of time investment neccessary for mastery in a lot of these software packages can range from little to a VERY significant amount. Because of this I feel it's important to be lead in the "right" direction to make sure you don't spend time in the wrong areas, or learning some software that might not be all that useful for you later on (*coughs* Frontpage *coughs*).

Where you should start greatly depends on what you plan on attempting to do, and how deep you're going to dive in. For a moderately professional, clean looking web site without a lot of automation or intensive animated graphics you can probably get by with some basic knowledge of html, ability with a good WYSIWYG editor, and an image editting program. On the other hand, if you're someone that's looking to build something that will really wow your audience then you might consider spending some major time and developing some animation skills with a program like Macromedia Flash. I personally always spring for what I believe will bring me the greatest amount of profit with a minimal amount of effort, and because of this I usually end up spending all of my time diving in deeper with ONLY my WYSIWYG HTML editor, and my image editor.
