He had to sacrifice both eyes to gain the equal wisdom of odin however when odin hung himself he only went to the brink of death while thor travelled past that and I believe actually died while doing so and in turn gained more power then odin from the runes.
iirc thor sacrificed both eyes because the sacrifice had to be unique. since odin already sacrificed one eye, thor had to sacrifice both. or he could have sacrificed a leg or an arm as long as it was unique.
as for the hanging, yeah, i believe odin just almost died while thor did die and overcame death thus becoming more powerful.
