In response to question 4, generally speaking the job markets vary on your location.
Over the last 30 years I have been an editor/motion graphics person at 2 large facilities in the Western US. The economy has shut down lots of large facilities. Also there is much more competition since now you can own NLE and Effects software relatively cheaply.
Who you know and the skills you develop are probably the best ways to get a job doing what you love.Living in an urban area will probably help as well.
The last facility I worked at for 9 years has just about shut down here in Las Vegas and after being layed off I am still looking for a full time position. Times are tougher for editors now then when I started many years ago.
