Front suspension suggestions for better tracking

Little bumps can make it wander if the idler arm is even a little bit loose or worn. Yes if the toe is "out" it will turn at speed like no ones business...but will wander going straight/track bad.. toe "in" will make it track nicer but cause a tittle built of oversteer.
I used to do alignments for Goodyear Express Tire at one point before the machine shop
