   The operational altitude of the orbiter is 115 miles to 600 miles.
I would imagine at the upper limits maneuverability is limited due to
fuel requirements to get back down.  The shuttle will remain with the
ST for the duration of the mission (about a week) to check out its
systems and directional (pointing) stability.

   Also, the computer components of the ST are modular, designed to be 
popped in and out for repair.  The expected life of ST is 15 years.
