It's really easy to be a Monday-morning, armchair quarterback, isn't it?

To Ara: The tool kit is a lot less dense, and a lot less massive, than the ISS, so it experiences a lot more drag from (the extremely thin) atmosphere in that orbit. So it will come down a lot faster.

ISS does have thrusters, and it usually gets a boost from the shuttle before it leaves.
