Yes. Look up the variables nspinor, nspden and spinat.

Using nsspol 2 gives both the spin-up & spin-down bandstructures.
Look into the _EIG file. You will find the energy values for spin-up, followed by spin-down.

Could you please attach your input files, and tell me the pseudopotentials you are using.
I may understand your problem better if I could run the files & see the outputs.

ngkpt creates a uniform grid & then applies symmetry operations.
if u look at the kpt list, it wont look 'uniform'. lots of k-points would have been removed due to symmetry.
