Depends on the year. I know 1999 and 2000 idle at 725, and 2002 idle at 800. If I had to guess 1997-2000 idle at 725, and all later years idle at 800 RPM.
Both, but most importantly in gear
My wifes car has stock heads and cam, and after her "tune" it idles right around 600, which makes the "LS1 surge" a lot more evident
