Electrics are easier to play, so it is easier to learn on an electric. I am not sure easier is better, but if it is more fun, maybe you will practice more and THAT is better for sure.

I would highly recommend getting face-to-face-lessons. That way you won't develop a bad habit and have to unlearn it later (like I did, holding the pick with 3 fingers - took me a full year to unlearn it).

I don't know about that other stuff. Ask John Edwards from scifi channel.
