And where precisely are these two 'extra' Soyuz going to come from?

Krikalev was acting as a saleman: "For a true safe haven that works, buy
2 soyuz now and have them always ready to be launched if needed to
rescue shuttle crews".

While the Soyuz solution does deal with saving human lifes, it does not
deal with any cargo uplift for spare parts to save the injured shuttle.
And that is where the backup shuttle really comes in handy.

In the short term, will they be doing anything to make PMA3 usable ? Are
there any possible PMA3 locations that would allow the SSRMS to move the
injured shuttle from PMA2 to PMA3 ?

In terms of sufficient storage and general space, I still think that
NASA should have spend those 2 years strenghtening one MPLM into a
permanent fixture to the station.
