The animation tools and the workflow to use them for the most part got left alone in the 2.8 releases. The anim courses below for sure are relevant still with the possibility that a hot key or two has changed. If you run into trouble give a shout out and either the community or CGC crew and help you thru it.
Blender Animation Bootcamp
Animation Workflow & Body Mechanics
Demystifying Lip Sync Animation
The rigging tools have gotten some updated features but I don’t think anything that is covered here has changed. Again, if you get lost throw a shout out.
