In just 20 minutes you will be introduced to 3 things I think are integral to the future workflow of web development. I recently used Codekit (sorry Mac only) and this is a must for you to check out. It works seamlessly with Sass, the Chrome browser (which is the best browser in my opinion for web development) and Compass.
Jade is a great way to start typing your HTML fast. I use Emmet in Sublime Text 2 and that is super awesome but if you start using Jade in combination with Emmet, you will be amazed with the increase in your productivity.
Sass is something you need to check out. It is amazing. CSS is fun again!
