Need help with customizing WP Revolution theme??

I would like to use the Revolution Tech 2.0 theme on my site, but I'm having a bit of difficulty trying to configure it. Is there any sort of tutorials for this theme. I'd like to use it as a 3 column style and do some other editing. Is it pretty much going into the theme editor and changing the specific code or is there any sort of plugin to do it easier?

If you want to do serious customizing you're going to have to change the code. I'm not familiar with that particular theme but I'd say changing the code is your only option, there generally aren't plugins to customize themes.
