I would try out an M90 spring from either Guarder, Systema or Prometheus. It should give you the result you're looking for. Metal bushings are OK too, but not REAL necessary with only an M90. Lots of guns from other manufacturers use nylon bushings with an M90 and run for a long time.
You don't need to change anything else.
