Do satellites orbiting earth travel in a system of space-lanes so that they don't run into each other?

No not really. When satellite orbits are being designed, they are carefully checked such that they don't intersect with the orbits of existing satellites or debris in space. 

One special orbit is the geostationary orbit where satellites must be 35,786km away from the Earth and directly above the equator in order to stay in the same position in the sky with respect to the Earth. This means there is a limited amount of space in that orbit for satellites to position themselves safely without risk of radio interference and collisions. The ITU (International Telecommunication Union) oversees the slots in the geostationary orbit and the radio frequency bands being used.
