Ok, so @itcrowd has some very good questions that the answers will definitely guide the resources recommended to you. However, it may be difficult to answer as a thoughtful and complete answer to each question, for you, will depend on you knowing some stuff already.
So on that note, a great place for you to start figuring out what you want to do with EE is to watch Dave Jones over on the EEVBlog YT channel (https://www.youtube.com/watch?v=6a-jcaTn170), then go and join the EEVBlog forum.
