Das is a great player and IIRC he plays without most of the automation off, so his videos should expose you to most parts of the game. The issue is that Let's Plays of DW are LOOOONG. =P If you need help the forums is always a great place, there is a thread called the "Guide to Guides" with links to guides on many areas of the game, and you're welcome to create a thread with any specific questions you have.
Some random tips:
The default ships designs are serviceable but rather suboptimal and once you feel comfortable you should redesign them yourself.
Your homeworld will contain the vast majority of your population for a very long period, and this has many implications. Population is connected to build speed, so don't try to built a large space port on a fresh colony. Low taxes boost population growth, so keep them as low as possible until the planet reaches a good population - short term pain = long term gain. Again: the homeworld will supply 90% of your income via taxes, but if you can leave the rate low for awhile it's population will grow even bigger, and you'll get even more income from it.
Keep an eye on your private sector even though you can't directly command it. Mining stations are built with private money, and if it goes bankrupt, that will effectively end your game.
Some people like dozens and dozens of explorers and constructors, some people like less than a dozen of each. Find what works for you.
If you value your sanity, set auto-retrofitting on all stationary structures to OFF (e.g. manual retrofitting only). This will keep mining stations, etc. from perma-disabling themselves because of the private sector's inability to deliver small bundles of many different resources to the correct place.
