It's kind of hard to list exact steps because there are many choices along the way.
the basic steps to set up a new installation of wordpress are to:
1 - use 'manage domains' in the panel to configure the domain or sub-domain as fully hosted.
2 - use one click installer in the panel to install wordpress to that domain or sub-domain. Pick Custom (and not Simple) for the one-click install. The difference is simple uses files stored in a central repository, where as custom stores the files in your directory. This is important if you ever want to use (now or in the future) a theme or other plugin not included dreamhost 'simple' configuration.
3 - the installer robot will email you some information, use it to complete the next part of the wordpress install in your browser.
As far as the transfer of your blogger blog, i'll let someone else comment... I don't know if there is a way to export and import into wordpress or something similar.
