This is a question for someone at your program. There is no way we can answer it here. In general, if a skill set or some courses are required for a certain job or career choice, it would probably be advisable for you to learn it. Or at least it is possible that not having the relevant skills could limit the jobs you might be a strong contender for. In that case, it would seem smarter to take the courses so that you are not hindered by their absence from your transcript later. That said, you should really consult with someone who actually knows your program and the field you are planning to enter, who can tell you if the particular courses you are considering are actually important or if there are other things that employers care about. So -- talk to your advisor, grad secretary, or your program's DGS.
