No one is going to set out a roadmap for you to follow that will be sure to work, and if they do I would take it with a big grain of salt.

You'll have to immerse yourself in a job and do trial by fire. Give it your best shot.

You don't need to know everything to program. You should be able to pick up on new things quickly, and have an ever-expanding area of expertise.
