I directly started with Haskell, but had some difficulties with the functional concepts! this is why I second the idea of michael_dorfman. I think it will help you a lot to understand everything better. and I personally like video lectures a lot. not that I'm lazy and don't want to read, but sometimes, when something is explained visually or by a specialist in the specific field, you just get it better in your head :)
