One thing about C4s in particular: you sit almost over the rear axle line and every time the rear starts to feel light, you really feel the yaw compared to most other cars. When I was autocrossing mine, it took a bit of getting used to because I would be convinced I was going to spin and yet the car was still very "savable." Part of what you're feeling might just be that. Speaking of which, track days are fine but I would strongly recommend autocross competition to develop feel for the limits (and beyond) and car control skills. It's a much safer venue and you actually get lots more practice at these things in a few runs than in a whole track day.
And yes. There aren't a ton of auto cross events around but englishtown has their small road/drift track that I think would be suitable to get some practice on. Only auto cross one I know of is the events held up at metlife which I think are scca but that's a hike for one of the few weekends I get off. E-town is a 15 minute cruise and I can do that during the week lol. We have a big old abandoned parking lot nearby I've thought of mapping out and practicing on too just to get a feel on when it'll skid out in say a figure 8.

I just ordered a complete set of Super Pro bushings from C&S Corvette. Reasonable price, friendly customer service, fast shipping!
Half shaft U Joints I have been using Spicer 5-3615X that are coated for aluminum drive shafts.
I just did my third set of half shaft U joints and on the last two cars I did them on, they were pretty toasted.
Wheel bearing hubs I would not do unless you can feel play in the wheel bearing hub itself via the "3 and 9 o'clock" test. Car in the air, wheel and tire assembly mounted, grab the wheel and tire assembly at 3 and 9 o'clock or 12 and 6 and try to wobble the wheel and tire out of its plane. Make sure that nothing else in the suspension is allowing the movement and only if it has play there would I replace. The issue is that there are simply no good high quality wheel bearing hub replacements available. The ones from parts stores and eBay and rockauto while serviceable, are not great.
That being said IMO it sorta depends on miles and how much hard cornering the car has done.
