It depends on what type of job you are looking for. If it's a CFI or part 91 piston job, all that stuff might help except for 737 training. I wouldn't spend money on that unless you have enough time to qualify for a 737 job.

If you are entry level, networking is going to do WAAAAY more for your job prospects than endorsements. Pretty much every 1500 hour pilot has all those endorsements anyway.
