Rega Planar 3 upgrades help.

Hi guys, i got a local deal cash on a Rega Planar 3 mint condition for $200. I would like to bring this table to a diferent level of performance. I think i will enjoy the upgrade process. I just want to follow what others had done. I do really appreciate if you take your time to share some experiences.
I am considering no necessarily in this order.
GT reference SP.
GT Delrin Platter.
Rega reference white belt.
Motor kit upgrade.

Thank you all.
