Your question is really beyond the scope of a few Reddit comments. This is a highly technical and complex field to get into. I suggest finding a good Hermeneutics text and working your way through it.
If you have an Android phone, you should download RTS Mobile, go to Lectures, Find Old and New Testament, and listen to Robert Cara's lectures in Advanced Biblical Exegesis (which isn't really that advanced). This lecture series really helped me to grow in my understanding of Hermeneutics, and Cara does a great job as a lecturer. If you don't have Android, I believe these lectures can be found on iTunes University or something (I'm not an Apple guy).
Sure! Which phone do you use?

If you still jave trouble let me know :)
The best would be to listen to bible colleges or seminaries. Here are two that let you listen to the lectures for free.
I know reformed theological seminary has all their courses available on an app and maybe on itunesU. I've listened to most of them and I really enjoyed it.
Ryan Reeves is a Reformed Gordon-Conwell history prof who makes youtube Christian history videos. Also Matthew Everhard makes bible-review videos that make me envy. If you are laid up in bed for longer than a couple YouTube videos can help, I suggest you check out the RTS mobile app which has dozens of full course audio-lectures, and even some video-lectures. To me, the highlights in the RTS app are Michael Kruger's gospels course and Ligon Duncan's Covenant Theology course.
Edit: I pray your procedure goes well! Lean on the Lord in your troubles.
