Hi
Looks like a full recipe on how to make a website
Ok for start. If You have already installed a quickstart for creative template but You want to have a different template instead the question is if You want to keep the content of the installed or need to use the demo proposition for real design template.
If You want to use the content from creative template please simply download a template package only and install it using a joomla installator.
If You want to have a demo content from real design template than it would be easier to remove the website You have now and install the full quickstart one more time. If You will make it like that than there will be no problem with content not matching module positions.
Each of the (lets call it) boxes You can see on a website is a module. You can download and install (using joomla instllator) any module You want. Here is a link where You can see what modules are available:
http://extensions.joomla.org/When You have modules choosen or You want to modificate an existing one, please simply go to modules manager, edit the one You are interested in and configure it's settings.
For example Image Show GK4 is a module for rotating slides. And here is an instruction about how to use it:
https://www.gavick.com/documentation/jo ... -show-gk4/Using modules You can embed a video (my plugin for that favourite
http://extensions.joomla.org/extensions ... allery/812, You will find a detailed documentation on how to use it on it's developers page), add a newsletter form (

If You want to rearange the modules You can use module positions map available on each demo page of our templates
