The poll has 3 questions and 4 answers. If I choose "yes" or "no", I am not sure, which question it is meant for. And questions 2 and 3 are opposite to each other. Please clarify the poll with only one question.
I don't have a CS degree, but it didn't affect my career at all. I feel that CS would be helpful for interviews and expressing the problem using CS terms. I used to read up on basic CS stuff and talk to CS friends to gain CS knowledge. As long as, one can read and write english and familiar with basic math (logarithms, algebra, calculus, probability etc.), CS is very easy to pick up.
