The biggest suggestion I can offer is learn HTML.
Even if later you go on to use WYSIWYG editors (what you see is what you get) - you will be ablet o then look at the HTML those programs spit out and be able to find problems and places to trim the code.
Front Page does things to it's code that cause problems in browers other than IE - that's a common problem with any editor.
Learn the basics first. I agree that
