Even though your site's browser stats show that people are using higher resolutions, you're assuming that everyone surfs with their browsers maximized. My screen resolution is 1600x1200, but I rarely have my browser maximized. It usually takes up the left half of the screen (800x1200). I could be really weird about this, but I think a lot of people do similar things. In fact, I know a lot of web designers do similar things. We like multi-tasking

So even though you may not end up with a site that fits perfectly in 800x600, you might want to think about what parts they see.

If you're willing to learn a bit about scripting and/or programming you could try BrowserHawk.

It'll tell you all kinds of stuff about the browser and plug ins. Then you script your page to automatically adjust for the display size.

tool bar > view > text size > that screwed your site
use flash, they cant screw with that

I did finish my first homepage a few days ago, and dreamweaver was absolutely the clue. First I started to code in pure html and had a "html4 for dummies"-book for help. So I learned the basics of html, which helped me a lot to understand and use dreamweaver later on. With the knowledge about html and the help-function of dreamweaver I finished within one day, for what I spent three weeks before. so my advice: learn html-basics.
