There is really no secrets to the front end. I like to use a small dab of Trinity Red stuff grease on each king pin. The L4 pins are pretty smooth right out of the box. The only place you want to make sure they really smooth is the pin sliding through the lower arm ball.
Not really a dimension to go by. Just set the shims (on top) so there is little to no droop.
The best thing you can do is make sure when you build the front is to make sure both sides have equal ride height. Most of the you need a thin shim under the lower a-arm on one side of the car to make it even.

take care
