Best starting point?

I would honestly say, watch GothamChess or Hikaru videos. I find GothamChess fairly instructive. Find a strategy that works for you or that you seem to like, and test them on bots to learn different variations and how the game plays.

I would start with two simple things:
1. Learn opening principles (this video is worth 8 minutes of your time - Chess Basics: Opening Principles)
2. Then begin to learn basic tactics. Mostly, you just need experience at the beginning -- experience seeing the board so you don't hang your pieces all over the place.
3. Play slow games (30 minutes or more) so you have time to see the board.
Lots more to do, but if you are as much of a newbie as you explained you were, the above three will take a while. Check back in and tell us how it's going!
