For youtube, I recommend ChessNetwork. He's a self taught GM that explains his thoughts as he plays. He also has a beginners series to get you in the proper mindset. Really good guy, but a bit mysterious...
For actual playing I recommend something fast like 3min/0increment or 2/1. It kinda of resembles a video game at that point, where your knowledge and speed is helpful, you get to play a lot of games since they're short, and you don't have to live with your mistakes for very long if you mess up
