Or are you after what psi when hot ? Been a while since I ran them. If they're like a slick then it's about 32psi hot but I think they're still more like an R spec and might want a bit more. Search in the Racing forums.

Car weight???
I've found that ~37-38 gives me good temp spread across the face of the tire on my stock-weight car. Temps get to ~190 on the more-loaded side of the car, and ~170 on the unloaded side.
If you don't have a fair amount of neg camber you'll eat through the outer shoulder in no time.

The irst thing you should do is to review the information on Hoosiers website. It is also important to set your temperatures in the morning when they are cool, then keep the tires out of direct sunlight to avoid thermal gain at different levels. Cover your tires or use a tent but keep them in the shade all day unless out on track.
Check tires using a probe type pyrometer as the its necessary to check below the surface. To get accurate temps it is necessary to come into the pit hot, anything after that is a guess. Also record the track temperature and ambient temperature. Get yourself a small spiral notebook to keep track of your temperatures.
I would also recommend reading Michelins race tire guide, it has some excellent suggestions and points out some common mistakes.
Slicks cost a lot of money and tires are the most overlooked go-fast accessory. To get the most out of them it requires you to learn and follow some basic rules. You will be rewarded with a better experience and faster lap times if you take the time to learn.

3.6 to 3.9 front
2.4 to 2.6 rear
It's pretty much the same but we look at the temps on track. Different tracks require different camber, sometimes we run asymmetrical. Example is Mid Ohio where you have a lot of right hand turns and you don't want to scrub of the inside of your inside tire.
