Learnk8s.io is great. The material is insanely good. Register for the advanced course, it includes the basic too. Buy a 12 inch tablet if your budget allows it, one that allows a stylus. It helps you read and markup pdfs. Don't buy physical tech books unless they're classics. You can also search through soft copies. I use the Samsung Galaxy Tablet S7+. I've heard good things about the iPad Pro also.
