Thank you for using our services.
You are on the right path. Sitefinity does have configuration section handlers. In fact if you take a look at the declaration of all configuration sections in the web.config file you will see which sectiion handler is responsible for which section. However for generic content modules for example it is easier to read the default settings from an instance of the content provider. For example News content provider. Here is how to get the default URLrewrite format:
//instantiate a content manager with the NewsProvider
Telerik.Cms.Engine.ContentManager cntManager =
//get the default url rewrite format for the news provider
UrlRewriteFormat = cntManager.Provider.UrlRewriteFormat;
