  The differential cross section and spin asymmetries for neutral pions
produced within the intermediate pseudorapidity range 0.8 < {\eta} < 2.0 in
polarized proton-proton collisions at sqrt{s} = 200 GeV are presented. Neutral
pions were detected using the endcap electromagnetic calorimeter in the STAR
detector at RHIC. The cross section was measured over a transverse momentum
range of 5 < p_T < 16 GeV/c and is found to be within the scale uncertainty of
a next-to-leading order perturbative QCD calculation. The longitudinal
double-spin asymmetry, A_LL, is measured in the same pseudorapidity range. This
quantity is sensitive to the gluonic contribution to the proton spin,
{\Delta}g(x), at low Bjorken-x (down to x approx 0.01), where it is less
constrained by measurements at central pseudorapidity. The measured A_LL is
consistent with model predictions. The parity-violating asymmetry, A_L, is also
measured and found to be consistent with zero. The transverse single-spin
asymmetry, A_N, is measured within a previously unexplored kinematic range in
Feynman-x and p_T. Such measurements may aid our understanding of the on-set
and kinematic dependence of the large asymmetries observed at more forward
pseudorapidity ({\eta} approx 3) and their underlying mechanisms. The A_N
results presented are consistent with a twist-3 model prediction of a small
asymmetry within the present kinematic range.
