Is it just me or do you think the JS lessons especially at the end are very confusing and not well explained?

Ok here I am watching the js videos and taking notes. The first 2 or 3 sections were easy to grab but the last three doesn't make any sense. For instance, Jim is talking about methods and how it is used but he goes really fast through them leaving me wonder "what the hell just happened and why did he do that?". Does anyone else experience anything like that? As a beginner in web programming, it is hard to listen to him and understand every single programming word he mentions. It would be much better if the videos were a little more practical. All I did was play with the console and nothing else. Don't you think it would be better if he showed an example on the webpage itself on how the specific method or the function can be used. He gave an example only once on one of the methods and I understood it instantly. Other than that, I felt like I wasted 5 something hours just listening and really doing nothing.

That being said, I am thinking about grabbing a javascript book preferrably a one which covers a little bit of jquery too. What do you think about it? Any book recommendations will be greatly appreciated.

I want to be a front end web developer who mainly works on html/css/javascript/jquery. What other languages do I need to OR should learn to be able to be a pretty good front end developer? Should I learn photoshop or illustrator for the initial design? Did I miss anything?

Thank you. All answers are appreciated. The more detailed, the better. :D
