Can you please tell me which repair is more critical for a 2002 RL: (1) Power Steering Pump leak, (2) Rear main leak, (3) Cam plug leaks?

Thanks DaveJM! Yes, all the leaks are minor at this point and very costly, hence my question for the group. Don't have the $$ to do it all. I'll focus on the Power Steering pump leak. Appreciate your recommendation.

Thanks pushrod! Appreciate you taking the time to respond.
