My recommendation would be to upgrade the arm first - Kuzma 4Point11 will improve the performance of your existing TT/cartridge fundamentally across the board. Do the cartridge later.
Cartridge options - Kuza CAR50 ( massively better than CAR40 and underrrated in my view ), Phasemation - very even handed balance across the spectrum, Mysonic - more dynamic, a little coloured through the midrange in my experience The best choice is going to be determined by any speaker colourations that exist, and therefore whatb are you trying to achieve in the final presentation.
In my view the EMT's are quite course and not particularly transparent compared to these others.
