Alternative path:
1. Remove clutch helper spring

2. Check pedal height adjustment, previous owner may have messed with it

3. Flush clutch fluid
If you're not happy after those three then go buy a clutch.
I would also suggest performing the 60k tuneup before lightweight flywheel to increase engine responsiveness, spark plugs and air filter may be at the end of their usefulness and can perk an engine right up. Sloppy shifter feel depends on what's happening, if it's the transmission moving around yes those bushings will help, if it's the stick feeling loose then you'd probably want to look into replacing the springs, I believe "mtec shift springs" are the popular choice but there may be alternatives.
63k miles on my original clutch and driveline, hundreds of hard launches 5x track days and I have no complaints or need to buy parts for them. I pulled the clutch helper spring a few months back and it was a nice stiffening of the pedal but I got used to it in a week or so and only notice jumping back and forth between cars.
Edit there's also the clutch slave cylinder swap to improve feel, not too expensive.
