Polish translation -- also, last name.?

Travel Info
I know I am of polish decent but lost contact with my father's side of the family -- does anybody know the full length and origin of the last name Kurek?

Also, what does "Wy i zadnego innego" mean?

Travel Tips

it seems to me that Kurek comes from kura wich means chicken, maybe your ancestors were farmers?
wy i zadnego innego means you and nobody else but gramatically wrong, it should be wy i zadni inni (plural) or ty i zaden inny (singular)

Others
it means you(plural; group of people) and nobody else. and no idea about the name except for kura, which means chicken. take it from a guy who was born in Poland.
