Why is the P6 relocation a shuttle task and is not performed by the ISS
anytime from now?

Good question.  Seems like you would have everything you might need to do
the job on the station, unless the shuttle brings up special tools to hook
up cooling and power lines etc.

Probably a matter of training and practice opportunities for shuttle personnel.

Well, when the astronauts hooked up S3/S4 it crashed the Russian
computer systems, so doing these big moves when the Shuttle is around
is starting to look more and more like a good idea.

The relocation will be done when there are a lot more eyes and hands
on the Station to help out. Two spacewalkers, one astronaut operating
the SSRMS, one watching the spacewalkers on monitor, one watching the
SSRMS and P6 on monitors, one overseeing the Station for more computer
glitches...

I think that's the real reason. P6 relocation involves an EVA and
complex SSRMS ops. With two EVA crewmembers, having the third crewmember
handle both SSRMS and IVA duties without backup is just too much of a
load. With a shuttle there, you can have five crewmembers involved (EV1,
EV2, IV, M1, and M2).

Yep.  Makes total sense.  Not to mention the guy floating around from window
to window taking high res pictures as a secondary job.  If there is one
thing I've learned in watching all of these assembly missions is that there
is a lot of choreography going on when moving and attaching these
components.
