Am I done with learning?

It all depends on what job requires. Some of the front end jobs I've interviewed for are asking for bootstrap, LESS, SASS and grid based layouts. Others want PHP, Drupal, Wordpress, react.js, etc. The key to it all is you never stop learning. :) Once a developer stops learning, your skills will get old real fast. I know from experience, hence why I am updating my skills at treehouse.

With all that said, look for job postings that align with your skills and go for it. But make sure you know your stuff. A lot of companies I've gone to give timed coding tests, and they tend to want to see coding samples/portfolio.

Depends. Do you have a portfolio? If you want a job you will want one. If you don't, find a site to make, even if it is for a company that doesn't exist (You invent it, including branding). This will show what you are able to do without following a teacher or book. This gives you the opportunity to use documentation, Q&A sites like Stack Overflow, and learn new things on your own.

As might see from the last sentence, you don't stop learning. What I mean by that is you learn something, you keep up to date on the technology to do that thing.

Also, do you do design work, development, or both?
