Audio/Video Capturing and Editing

From our list:

• Video Storage
• Video editing (software/training)

For video editing I'm going to recommend two. The first is Davinci Resolve and is available 
here -> https://www.blackmagicdesign.com/products/davinciresolve <-
Davinci is pretty advanced so capable of some incredible effects, even at the free level (there's a paid version too, $295.. worth it later on if Davinci works well for you)

There's some good online resources for working with Davinci..

The second editor I'm going to suggest is completely free and it is KDenLive, it lacks all the bells and whistles of Davinci, but it's free, well known and gets the job done.

Here's a youtube trainer for KDenLive..
