I would look around at jobs you would want and see if they require any of these certifications and those would be the first to pursue! For instance, my job REQUIRED NRP before interviewing. Some positions include the training in orientation, but hospitals can be picky now :-/. I also have ACLS and PALS because I wanted to be able to market myself in other areas if necessary, but they do not apply to my position now. Great learning experiences, but I will probably not be renewing them.
EKG and pharmacology cert is great to do before ACLS, I would not have been able to participate without it. If you want to do SOMETHING, I would say ACLS.
