My suggestion is to go for something you never tried so yes, Python with django could be a good thing if you never used them and for javascript try dropping and going for angular/backbone/ember. For the resume I think it depends on what you want. I like to have a bit of everything so if I want to change field I can. But that means that I am not yet a super expert on anything. I think that if you became truly good at one thing you could ask for a higher salary but you will be stuck with it and might be harder to find a job. But this is just my personal opinion.
