Yes the toe is the direction the wheels point. Toe in will have left tire pointing right and right tire pointing in. Now if you have toe in on the left and toe out on the right the car will want to go right. Camber is how close the tops of the left and right tire is compared to the bottoms....can also affect which way the car wants to go.
IIRC there is a special toe bar or camber bar or some special bar that is need to align some MB's that the common shops don't have.
