Just keep in mind of you do use the RL you should never run it without installing the sample data.

The RocketLauncher should never be used unless the sample data is installed. The whole point of the RocketLauncher is to give users a way to get up and running quickly by replicating the demo. All of this is accomplished with the use of the database information in the sample data sql.
Without installing sample data, the RocketLauncher is not only the same as a default joomla install with no sample data, but it will actually be badly broken as the launcher contains all of the files and directories for the extensions used in the demo, but none of the database information will be present.
This means that if a user installs the RocketLauncher, but does not install the sample data, most of the extensions will not work as they won’t be detected by joomla, and attempting to install them will cause errors and fail because while Joomla doesn't see them, the directories and files are there.
Basically, there is nothing to gain by using the RocketLauncher without the sample data, and it will cause a whole lot of issues down the road.
So, basically what you stated is correct, RL with the demo content, then edit / delete the content, or a stock install of Joomla with or without the sample content, then apply the template and install all the extensions and go from there.
But then again, with a stock install of Joomla and the sample content, when you apply the template, the Gantry positions don't match the Joomla positions, so you have to move stuff anyway...
My method of choice,
code.google.com/p/gantry-framework/downloads/list
The RL with no sample data (this version is the stock install with the Ganrty framework)
Then apply the template of your choice and its extensions.
What you will end up with is a clean install of Joomla, the Gantry framework, your template, and extensions installed properly with no conflicts to worry about (as mentioned above).
But... you are going have a 'naked install', i.e., there will be no content for reference editing.
So, what I suggest is to install a spare copy of the template with the RL and the sample content (on you localhost or a sub folder of your site), for reference.
That way you can set up your site 'clean' without having to edit / delete sample data, but still have reference to it to see how the back end is organized and be able to access to the code in the Articles and Modules.
