I have been a member of AANAC and RAC-CT for a long time. I recommend joining and getting certified. if your company will pay for you to go to one of their classes I think you learn alot more then doing online if you are new to MDS. Even though I am certified I am going to a class the end of September just to hear all of the changes and be able to ask questions. (Unfortunately I have to pay for it all myself, so I just added a few days and made it into a mini vacation) Good Luck!!
