Setting for Planar 3 RS Nd5 with Rogue RP-1?

Hello. I have an incoming P3 RS. Will be used with my Rogue RP-1. There seems to be some adjustable settings in the RP-1 for the Phono amp. Cartridge loading and Resistive loading. Not exactly sure what they do? The preset is Gain 43dB and loading set at 47K. Does that seem ok for the Nd5 Cart or do i need to futz will the settings. TIA
