A. Use google, most (dare I say all) plugins have a page describing how to use them, in fact when you install a plugin it has a little question mark next to the name on the file manager, when you click that it takes you to the plugin page which sometimes contains a guide.

B. We have a knowledgebase with some guides on it for plugins: https://playerservers.com/knowledgebase
This does in fact contain a guide on WorldGuard (https://playerservers.com/knowledgebase/article/7-how-to-protect-your-builds-using-worldguard)
