I took a 2 hour General Assembly course and found it incredibly useful - it sounds crazy but I feel like I learned 50% of what I needed to know about UX in just those 2 hours.
I asked some UX peeps what books they recommended and I purchased 2 and never read a single page (they were The Lean Startup by Eric Ries and Sprint by Google Ventures).
For web app UX, I found this 30 minute video extremely useful (great to see how a non-design person might make something, then how that same non-design person can change the primitive app they made into something very nice!).
