I would recommend that you go to Dave Ransom's homepage and get the 
predictive TLE for STS-81 based on a Jan 12 09:27 UT launch. There you will 
find the predictive TLE and you can download the State Vectors based on the 
planned mission profile.  You will have to download a program called Vec2TLE 
(also on his homepage) which converts State Vectors to a TLE to see how the 
orbit is planned to change over time.  Of course, download a current TLE for 
Mir to see the relative location of the two.  Mir supposedly made an orbital 
correction yesterday and plans to make another one on Jan 8 to raise its 
orbit.

a)Yes
b)Mir will lead Atlantis initially by roughly 16 minutes and that will 
decrease over time.

P.S. not much viewing of Mir/Shuttle AFTER launch from KSC but I would trade 
you places ;-)
