:You're welcome. On your talk page, at the very top, there is a welcome template. In the top left section, there is a box titled "Getting started". Click through those links. Also, if you look in the edit history of any article, you'll see a list of edits. To the left there are links that say (cur) and (last). The former will show you the difference (referred to as "diffs") between the reversion you're viewing and the current version. The latter will show you the difference between the reversion you're viewing and the version before it. By looking at diffs, you can view what changes have been made. That, too, will help you understand formatting. 

 :For references, check out WP:CIT. I don't usually use templates, unless I'm doing complex referencing, but they're good for beginners. Something you may be interested in is our adoption program. It's basically where some experienced users volunteer to help new users learn the ropes. Let me know if you have anymore questions.
