I would suggest you read the Lean Startup book by Eric Ries and perhaps browse thru videos at Udemy, several videos are free and they sell great content like the StartUp MBA, etc. I like listening to the This Week in Startups show every week and also to read Hacker News daily. Try to follow as many relevant people as possible in Twitter and also build a strong list of RSS to follow.
