Ok so first things first: Welcome @RichFarina to the community
Second, for your questions:
unfortunately there aren't much tutorials/videos about our apps out there yet, there are few videos/toturials showing the paypal plugin used alongside our other apps in our Funnelish Apps for Clickfunnels directory.
And you can talk to me obviously just reply to this post/ or tag me and will answer asap...
PS. The Paypal App is only part of a part of a list of other apps for Clickfunnels we have, which you get as well....
Hope that helps,
