There is no required amount of shims. They include them so that you can adjust as needed for your application as mentioned above.

The springs are set to height. The roller tips on intake set dead center and the exhaust are very close to center. Thats all i can tell at this point til i get them bolted on and get more parts. Do you have .090" to .100" of clearance between the rocker arm and the outer edge of the spring? Then you should be ok...

You can't change the rocker ratio, so the articulation remains the same as it follows the cam, so the shims can only be there to make sure the rocker arms sits high enough so they don't hit the outer edge of the springs when in motion...
You have probably seen a million sets of wedge rockers on here that hit the outer edge of the springs...Makes a mess of the aluminum rockers.

Centered is nice, but not important (unless the tip passes really close to the edge of the stem). 1. With the valve closed, the roller should be inside the center (close to the valley) 2. At 25% lift the roller is centered on the tip 3. At 50% lift the roller reaches its farthest point away from the valley, and stops 4, Reversing, 75% lift when centered again 5. Full lift returning to position 1
