1 . Really there are two things you need to get good at. First, there’s “rationality” itself, for which you should learn the math and learn about cognitive bias etc. Second, there’s the content of your beliefs; in other words, learning everything there is to know. So my answer for #1 is: find a big gap in your knowledge, and fill it.
2 . This is a very complicated question. In the big picture sense, the things that would be of most benefit to you would be things that have a huge impact on the future, like topics relevant to FAI or Transhumanism. You could work on improving the human lifespan and quality of life, or create something that will do that for you.
3 . If you’ve already done an undergraduate degree in AI, computing, or a field like that, you really should be able to just jump into a master’s degree program in fields like Mathematics. Another bachelor’s degree in a particular field doesn’t make a lot of sense, partially because the main point of a bachelor’s degree is to make you a well-rounded person and give you access to a wide variety of perspectives, and you’ve presumably already done that.
That said, some fields do expect you to have done a lot of specific work during your undergrad, so if you wanted to (say) go into a biotech-related field, you might need to do a bachelor’s in a related field first.
4 . Computer science is always fun. Mostly, it’s a long stream of interesting toy problems. Ditto for philosophy, but you really need to be at the right school for that to work. (Your generalizations aside, I must agree that philosophers who have done some programming seem superior, though I’m not a good choice for an unbiased opinion).
