First welcome to WT Betty and don't worry about being a novice we all were at one time.
You don't need to set the height at all on web pages. It's perfectly fine if people have to scroll a little down the page. But you can always set a height if your design calls for it.
The way I usually make sure my pages stay within 800px width is to set a container around all the code in my body. I use a div and I generally give it an id="page" Then I set the width on that div to be 760 or so px. So my basic shell code for the page might look like:
<html>
<head>
<title></title>
</head>
<body>
<div id="page">
all your body code in here
</div>
</body>
</html>
and I would set the width for that div in the css:
div#page {width:760px}
There are other ways to do it, but the basic idea is to set the width on the main container for all your code and then make sure that inside that main container your widths don't go beyond what you set for the container.
If you provide some code or links to the pages that aren't working I'm sure we can help with more specifics.
Hope that was helpful.
