Thorens TD-320 is not ab bad TT. If you're looking to improve the detail and sound stage then I would suggest you replace the cartridge with MC cartridge like Audio Technica OC-9 or Sumiko Blue point Special (nude body so be very careful of installing this cartridge.)
Hope this helps. If you want to stick with MMs, the better Grado also good choice.
If I have to choose with a limited budget, I would definitely replace the cartridge first.
