MobileMe Is Going Away - What Now?

I have had a handful of domains at Dreamhost for 10 years but have been using iWeb to create and MobileMe to host the sites.
Since MoblieMe is going away the end of next June and with it web hosting, I would like to move my sites to Dreamhost but are completely clueless on how to do that. I don’t even know what FTP means…
I would like to continue using iWeb, if possible. Any help and suggestions are greatly appreciated! THX!

There is a wiki page on using iWeb with dreamhost:

THX, Lakerat. Until now I have been using as my homepage, and have it cloaked through Dreamhost. Will the change from MobileMe to FDP Server automatically change my url to:, etc. for all pages? THX again!
