As far as I know, apache will look for it's files in the following locations:
Unless Mandrivia calls it html, in which case it will be either:
If /var/www/html exists, it may well be using that as the Document Root.
I'm not sure on that though - I use Slackware, which calls it htdocs.
Anyway, once apache is running, it will serve any files put in it's Document Root.
So yes, it is nothing more than copying a website to that directory and starting apache.
As root, start it with:
Which should fire it up on your machine on port 80, which you can check by going to http://localhost
and seeing what happens.
You can configure apache by editing the httpd.conf file, but you should consult the manual for that.
As for website IDE, I use the Mozilla Composer tool which you can get to from the menus in Mozilla itself.
