Also on old rims make sure the brake contact area is clean by buffing with a greenie or very very fine sand paper. Buff the pads also.
Your toes face forward, so "toe in" means the front will point at each other.
For "toe out", the front will point away from each other.
Alternatively, it's called "heel in", but this is usually never done with bike brakes.
