Bumpsteer - in the Losi is on the inner steering link ball placement. If you want the car aggressive when the weight is transferred to the front (ie - under braking) you run the ball in the high position. If you want it a little mellower then you run the ball in the low position. It all has to do with your outside front when you are loaded going into a corner. Set it on your table and check it out. It is a very cool little adjustment.
Camber links - control what is known as roll center. Your tires move up and down with the articulation of the suspension arm. Where that tire rolls over because of the upper link being shorter is your relative roll center. The more you shorten your upper link the lower your roll center is. The tire will gain negative camber quicker as the suspension arm is moved upward. As you side load a given tire, a lower roll center (shorter camber link) will take away (side bite) traction during compression and a longer camber link will increase traction.
Keep in mind this is what makes a car steer, rotate, grab and even traction roll. If you have too long of a link and the tire stays straight up and down you are going to get the side wall effect of the tire you are running. That can be good or bad and is totally dependant on the tires and wheels you run.
Hope this helps,
