Hi there awoodfield,
Funny you mentioned fast playing! We recently put a blog post highlighting some super fast songs. One of the best ways to learn is through learning songs so I recommend checking out "Blue Mountain Rag" which is the first song in the blog post here: https://www.guitartricks.com/blog/4-Super-Fast-Songs-on-Guitar-You-Must-Learn
For a more general look at fast strumming, check out Anders' rock strumming 16th notes lesson here: https://www.guitartricks.com/lesson.php?input=19994&s_id=1568
I hope that helps!
