How many and are they complete ready to fly?

All of the remaining truss sections are at KSC and progressing towards
launch. Pressurised modules at KSC are Node 2 and the JEM. Node 3,
Columbus (I think), the centrifuge, and the JEM logistics module are yet
to arrive, possibly due to lack of room in the SSPF.

On the Russian side, the FGB backup exists, but has presumably been in
storage without any progress since about 1998. Beyond parts of the SPP
(the old design, not the current version), I would be very surprised if
any other Russian hardware exists at all.
