What are the best books, workbooks, videos or classes you can recommend to help learn technical analysis and improve my skill at using it?
None. I have never fallen myself into such analysis because these type of analysis as they mostly never works. I dont like the idea of technical analysis in the crypto currencies because that model is completely different than the stocks etc. In this case, crypto currencies are very volatile one and mostly depend upon the factual analysis ! Facts like good/bad news, investment base, popularity, development and many more things to count on!
Its always better to go for the fundamental type of analysis and look for the current events which hamper the prices of currencies here.
