Hello, I use the normal 2,000 fpm, which at TOD will give you about 3.2 degrees descent angle. It is efficient fuel wise and comfortable for the passengers. 3,000 fpm is to steep.
You will not use idle power in the descent in a bravo because it is no a sleek airplane, you need power to keep your speed at near VMO in a normal descent, if not, the airplane slows down too much (straight subsonic wing).
The two seals in the citation bravo doors will keep the airplane pressurized in any descent regime without any problems, the auto press controller works marvels, even at descents of 4,000-5,000 fpm.
