There are few best practices, and the ones we have aren't explicitly stated in one universally agreed upon place.

My advice to you is this:

1. Focus on learning Javascript firs and foremost. Kyle Simpson's "You Don't Know JS" series is amazing: https://github.com/getify/You-Dont-Know-JS

2. Best practices are hard to come by, they essentially are: Crockford's Javascript The Good Parts, The Mozilla JS docs, and some styleguides on Github. Also lint your code through JSLint or JSHint.

3. Don't worry about build tools like Brunch, Gulp, Grunt etc. unless your job forces you to use one. If you're building small sites and apps, you won't need one.

4. When it's time to use a Framework, pick one and stick to it until you know it quite well. Frameworks are very different from one another. Backbone, Angular and Meteor.js are all quite different, but in the end they all do one thing, serve a web app.
