I've found the previous thread but still have a couple of questions.
It looks like we want as little as possible around 2deg?
In the tread if I understood it correctly (?) Jim said he adds a little to the side he wants to help the car turn in on. My next track is a right turn dominant track however there is a very important long left. Should I start with a little more left?
We don't get much practice so I have to be a close as possible.

Like many things with setup the answer is it depends. We have experimented with this a bit and have found that I am faster with more caster. Suggest you try a couple of different settings and see what works best for you.
I would also suggest that you play with this last after you are happy with toe, camber, and cross. There was a good write up JD did in the setup forum earlier this year you should read if you haven't.

Having never done an alignment before, I started working on my street NB to see if I could learn it.
So, just talking about the front cam bolts. Is it correct that the front one controls mostly camber and the rear one mostly caster?
I've found that my front ones are maxed out and the rear ones are about in the center. Should I infer anything from that? To get more caster, move the rear one in or out?

Caster is only adjustable on the front wheels, rear you control only toe and camber.

I think what Sphinx is talking about is front cam of front c-arm and rear cam of front c-arm.

Rear cam bolt all the way out toward the wheel is max caster. Rear cam bolt all the way in toward the motor is least caster. This bolt will also affect camber a little.
In short track oval racing I have heard of teams adding caster until the driver starts to complain that his arms are getting tired then back it off a little. Caster is said to affect turn in - more agressive turn in.
If you are new to suspension tuning, I would recommend you set both front cam bolts to maximum out toward the wheels and focus on other handling adjustments first. There is far more to be gained at the rear of the car for beginners.
