For camber is -1.8F and -1.2R a good set up for street use and occasional track (HPDE) use?
It's difficult to quantify in lap times. While they do have an effect in reducing rotational inertia and unsprung mass, your average driver will likely benefit more from seat time and experience, than a single mod like lighter wheels. Don't get me wrong, even little mods all contribute to a potentially faster lap time. If I were to put a figure on it, I'd guesstimate a quarter second on a 2 minute lap.

Harsher mounts will reduce play. Long term effects are still unknown, but based on anecdotal evidence from other cars, I'd speculate that it'll reduce movement, and increase wear on the components that are being stressed more by the lack of movement.

If you're trying to find a good balance of tire life and maximizing tire potential on grip, that seems to be a pretty fair amount of camber. Adjust according to wear to maximize life; adjust by pyrometer for maximum grip.
