[BlindMath] resource questions

Hi everyone, 
So it's come to my attention recently that there are some skills that I am going to have to start learning, and since I'm really not the best at self teaching, I was hoping that you might have some suggestions about how best to acquire these new skills. First, and probably foremost, I need to learn how to fully utilize excell, using a screen reader. I know some of you have offered to help, but I don't want to be a pain if I can help it. A second concern that has come up frequently, which I have been trying unsuccessfully to avoid, is the issue of learning to code. It has come up in a bunch of conversations now, and seems like it is a necessary skill to acquire. My problem is that, again, I have no idea how to go about starting to learn this. Do you take a class, use tutorials, read a book? Plus, how do you incorporate a screen reader in the mix. Finally, something that I'm keeping in mind for the future is learning how to use r. It sounds like it will be a good thing to know, but its not at the top of my list just now. Either way, I'd appreciate any advice you might have about how to learn, and where to go to acquire these skills.  
Thanks and best,
