The more positive caster you add the greater the self-tracking(stability) is. Only down side is the more positive you add, the higher the low speed turning effort is at the sterring wheel, and increased tire scrub.

5-7° is a good drag racing figure, if you can get enough adjustment to go that far, 4-5° is more typical.

It varies depending on year, trim, engine, 4x4 or 4x2, etc. But the generic figures I just looked up are +1 to +3 degrees.

I wouldn't go more than 4 or 5. Get your straight line stability with scrub radius (using offset) and toe. A scrub radius of about +1/4" and toe in of 1/16" should match up a pneumatic trail to keep you nice and stable depending on tire width.
