i'm not familiar with dw, but there should be some kind of "publish" or "publish to web" feature... once you find that it should ask you at some point of your website.. you'll probably need to tell it your webaddress (or ftp address), username and password...
publishing it is probably gonna be the easiest way for you, since you will also need to upload your images too...
if that doesn't work, then you should look around online for a tutorial on publishing your website with your version of dreamweaver... its a fairly basic task so it shouldn't be hard to find info on how to do this.
