Yes.

First, the nit picking corrections :-) Assassin and panopticon.

Yes you do.  Gallifrey does not travel in time, and the position of the
black hole would be known.  I suggest that it would become marked on
celestial navigators maps as just another spot to avoid.

The current theory of time travel is that when an object moves at
speeds close to the speed of light while in a gravitational well,
it can go backwards in time.  The weakness is that the object is
then inside the Schwartzkind radius, from which escape is impossible
without faster than light travel*.  Of course, these calculations 
pertain to only three dimensions.

*The schroedinger energy equation yeilds a concept called "tunnelling",
where a particle theoretically can move past an infinite potential.
All this is based on statistical extremes, but it does imply some
ability to escape the black hole, even though it is classically impossible.
For further details I suggest a four year undergraduate course in
Physics followed by a Doctoral program researching quantum mechanics.
