you've done well, although there's not much point in being able to use Flash unless you can design web sites - unless you want to specialise, and become a freelance Flash designer. The natural choice, for someone who works with Flash is Macromedia DreamWeaver. It's part of the same 'Studio' set, and you should be able to find your way around it with some practice.
Having said that, if you really are a complete novice (if you don't know what html is I guess you are), then something like NetObjects Fusion would be a good program to work with. You can use your Flash movies in NOF sites, and the learning curve isn't as steep as it would be with DreamWeaver.
