In my humble opinion, if it were me, I'd service everything from the flywheel back to the guibo, including the pilot bearing and all the shifter linkage bushings.
First, I'd invest in a Sachs clutch kit. Then I'd order a shifter bushing kit from whoever sells them. Lastly I'd have my flywheel resurfaced and remove the pilot bearing from the crankshaft hub.
Lastly, I'd take my transmission to a reputable and experienced 2002 suave shop. Dollars to donuts synchros are dead or dying. Sorry to be so blunt.
I'd pay anything required to have a smooth shifting gearbox while driving my freshly painted car.
